Universal Carbine Serial Numbers

Serial


I recently purchased an M1 carbine mfg by the Universal Corp out of Hialeah, Fl. They are since out of business. This carbine was mfg during the early 80s. The rear sight is an adjustable peep sight similar to the type found on military M1 carbines.

He goes on to say that 3,542 completed carbines were at the factory when taken over by Saginaw, Grand Rapids on Jan. 11, 1944 (observed serial numbers for these carbines are below 1,750,000). All other carbines, approximately 50,000 in number, were produced by Saginaw with IP receivers. Generally, serial numbers below 20,000 are the most desirable guns and some knowledgeable people consider serial number 25,000 as the end of generation-1 guns. The 'published' point for the end of generation-1 guns is serial number 100,000, but you could wind-up with a generation-2 gun starting after number 94,000.

Part I: The Early Years

Introduction & Overview

More than 426,000 carbines were manufactured by Universal Firearms over a 25 year period from 1961 through 1986. This was 10 years longer and more than three times the quantity manufactured by any other commercial carbine manufacturer. In the beginning the first Universal Firearms carbines were 100% compatible with surplus GI carbine parts, their carbines included many of these parts. As with every other commercial carbine manufacturer, as surplus GI carbine parts became scarce, Universal Firearms began using commercially manufactured substitutes. Unlike other commercial carbine manufacturers, some of the commercially manufactured parts used by Universal Firearms were eventually compatible with the Universal Firearms carbines only and not interchangeable with their surplus GI counterparts.

In 1967 beginning with serial number 100,000 Universal Firearms implemented a major design change to the carbines they produced. The design had been patented by Universal and the majority of parts were no longer compatible with their GI counterparts. The design change was significant enough that the carbine it produced was no longer an 'M1 Carbine'. What makes a carbine an M1 Carbine is the use of the design and parts of the original U.S. M1 Carbine, as set forth by U.S. Army Ordnance in the 1940's and early 1950's. The Universal Carbine retained the overall outward appearance and ammunition of the U.S. M1 Carbine, but the internal design and parts were a hybrid replica of the M1 Carbine.

Over the years many M1 Carbine enthusiasts and collectors have had a poor opinion of the carbines produced by Universal Firearms. Some complained about the design changes, some claiming the changes were unsafe as they did not meet the standards set forth by U.S. Army Ordnance. Many companies in the history of firearms have manufactured 'carbines' of various different designs, operating actions, calibers, etc. None comparable to the standards of a U.S. M1 Carbine simply because they were not based on the design and changes approved by U.S. Army Ordnance for the Caliber .30 M1, Carbine. Different is not the same as better or worsse. Confusing this issue is the fact the first 8000 carbines manufactured by Universal Firearms were of the same design as the U.S. M1 Carbine and most of the parts were interchangeable with surplus GI carbine parts.

Many owners of the carbines manufactured by Universal Firearms have enjoyed them for many years without encountering any problems. As with any other firearm, every part thereon and therein has a lifespan. All semi-automatic centerfire rifles share a number of common safety features that should be inspected periodically and when buying a used one. With a used gun, it's not the name on the firearm that matters as much as having a competent mechanic check under the hood before we drive it.

All of this should be kept in mind if and when you may encounter negative comments regarding the carbines manufactured by Universal Firearms. Investigations conducted by this author have found the majority of complaints were either not from first hand experience, did not include examination by a knowledgeable person to determine exactly why something went wrong (think semi-auto rifle gas systems, headspace, poor quality or worn out magazines), or one complaint was posted on an internet discussion forum and quoted on a dozen others making it sound like more than one. The issues discovered with a Universal Carbine or Universal M1 Carbine have been consistent with all commercially manufactured carbines, regardless of who made them. Refer to the Safety issues page on this website. Remember, a used semi-auto rifle requires more maintenance and safety inspections than most other firearms. Also keep in mind that if the carbines manufactured by Universal Firearms were as bad as the rumors, how did they manage to stay in business so long and make so many carbines?

Part I: The Early Years

The Beginning

War Baby Comes Home by Larry Ruth has a chapter devoted to the commercial carbine manufacturers. Included are nine pages specific to Universal's carbines. Some of the information regarding the company itself was provided by a person who had been affiliated with the company, did not wish to be identified, and who was interviewed by someone on Ruth's behalf. The interview was conducted after Universal's demise. The source indicated Bullseye Gun Works of Miami, Florida was founded as a gun shop in 1954, by 1956 or 1957 they began shipping M1 carbines wholesale to American retailers. Bullseye built their own receivers and barrels. Bullseye produced approximately 2000-2500 M1 carbines with their name on the receiver. Bullseye reorganized as Universal Firearms Corporation in the late 1950's.

Records of the State of Florida Dept. of State, Division of Corporations show Bullseye Gun Works incorporated in January 1960 with the directors as Jerry Resnick and Abe Seiderman. Bullseye Gun Works advertisements for carbine receivers, barrels and parts appear in Shotgun News, monthly, for at least the latter part of 1961.

Florida corporate records show Universal Firearms incorporated in Florida in June 1961. The articles of incorporation identified the directors as the corporate attorneys of the law office that submitted the application. The first indication of the actual corporate directors appears on the corporate tax return for 1962, dated July 1962. The president was Seymour Sommerstein, vice-president Robert Sommerstein, executive vice-president Jerry Resnick, and secretary-treasurer Abe Seiderman. The business location is indicated as 3746 E 10th Ct, Hialeah, FL. Starting with the corporate tax records for 1964, dated July 1963, Jerry Resnick no longer appears affiliated with Universal.

So far, the first indication that Universal was manufacturing M1 carbines appears in the April 1, 1962 issue of Shotgun News, within an advertisement for Southern Gun Distributors of Miami. Notice the ad states the receiver was manufactured from '4135 certified forging', meaning forged steel as opposed to cast metal.


Shotgun News, April 1, 1962

Gun Digest is an annual publication whose 1st Edition was in 1946. Each issue is divided into specific sections. One section includes chapters devoted to new firearms, a large section depicting current manufactured firearms and their information, and another section that is a directory listing that includes firearm manufacturers. The chapter devoted to new rifles in the 18th Edition pp. 225-226 (published in late 1963, for 1964) introduces the Vulcan 440 slide action .44 magnum carbine manufactured by Universal Firearms Corporation. The primary focus is the Vulcan, but the article states Universal also 'now offers' a commercial duplicate of the .30 caliber M1 carbine. Interestingly, the article states Universal's M1 carbine used all new commercially manufactured parts. This means Gun Digest's author had not examined the actual carbine. The rifle depicted in the photograph below the article is not the Vulcan 440, it's their M1 carbine, which the caption calls 'Universal's new M1 carbine' (below). The section on currently manufactured firearms does not include Universal's rifles. Universal Firearms Corp. is listed in the the arms manufacturer directory in the back of the book.

The statements in the Sloan's ads in August 1962 and Gun Digest's chapter on new rifles in 1963/1964, that Universal's M1 carbines were being manufactured using all new commercially manufactured parts, may indicate their M1 carbines were being advertised before they were actually available in any quantity.

In August 1964 Bullseye Gun Works notified Florida the corporation had been dissolved. Resnick continued doing business as Bullseye Inc. the gun shop. For further information on Bullseye Gun Works, refer to the page on this website dedicated to Bullseye Gun Works.

First Sightings

The first year the Vulcan 440 and the Universal M1 carbine are depicted in the Gun Digest list of current rifles is the 1965 19th Edition (published late 1964). The May 1965 edition of Shooting Times magazine pp. 71-73 includes a four page review of the Vulcan 440 carbine. Described are the many features it shared with the original GI M1 carbines. The only negative comments were the opening between the receiver and slide handle and Universal's claim it would work with 'all .44 caliber cartridges'. They confronted Universal about this statement, and it's clear the people doing marketing at Universal made some statements, in writing, that were not based on the operational abilities of the weapons they made. This should not be cause for criticism of Universal's carbines, these marketing tactics are unfortunately, often universal.

The first data for the Universal Firearms M1 carbine appears in the 1965 19th Edition of Gun Digest.

Example of an early Universal GI type M1 Carbine

Over the course of the company's lifespan, Universal changed the markings and their layout on their carbine receivers several times. The first set of markings used by Universal began at the beginning of production, continued until sometime after s/n 276xx, and changed sometime before s/n 405xx.

The First Alterations

The serial number on this first group was usually oriented with the bottom of the numbers facing the rear of the carbine and the top of the numbers facing the front of the carbine. Without any pattern or discernable reason, some of serial numbers were oriented 180 degrees (upside down) from the usual orientation.

A few very early Universal carbines have trigger housings manufactured during WWII for the GI carbines. Within the first two years, Universal began production of an aluminum trigger housing, somewhat similar to the GI trigger housings. Within a year, Universal redesigned their M1 carbine trigger housings again. Carbines with this redesigned trigger housing appear as early as s/n 1875x and appear to have been used exclusively s/n 445xx and later. This redesigned trigger housing was also manufactured from aluminum. The sides of the housing were thickened and run parallel front to back, giving the housing an overall rectangular shape. This trigger housing required the stock be cut to allow room for the larger trigger housing, making the GI stocks no longer interchangeable with the Universal stocks. The Universal trigger housing does not fit inside any stock other than the Universal stock, unless several significant modifications are made to the wood of the non-Universal stock.

Aluminum is not a metal that can be blued or parkerized like the rest of the carbine. Universal painted their trigger housings black. With continued use over time the paint may flake off. If this happens, it can be repaired by simple sanding and repainting the trigger housing. You might want to use a semi-gloss black bar-b-que paint or something like Brownell's Aluma-Hyde II, which is made for aluminum and a variety of other surfaces. The web page showing this product has links to several instructional videos that are worth watching, no matter what you use. They are a good example of how to use spray paint. They also have good on cold bluing and removing rust that apply to all products, not just their own.

The Shooter's Bible was another annual publication devoted to hunting, currently manufactured firearms, and accessories. The 57th issue 1966 (published late 1965) depicts the 'Universal .30 M1 Carbine', the 'Universal .30 caliber Pistol', and the Vulcan .44 magnum rifle. The description of the '.30 caliber Pistol' indicates the receiver was manufactured from '4140 certified forging'. The photograph clearly shows this predecessor of Universal's Enforcer Model used the GI type barrel band. The .30 M1 Carbine drawing appears the same as the one in the 1964 Gun Digest, clearly showing a GI type barrel band with attached bayonet lug. As you will see below, the parts sometimes help to identify the time period a particular Universal carbine was made.


57th Issue The Shooter's Bible - 1966 published in late 1965
Notice the hand guard, barrel band, and sights, these later changed.

Another early change implemented by Universal was elimination of the GI front sight that used a key between the top of the barrel and a groove in the underside of the top of the sight, with the sight held in place by a retaining pin. They replaced the front sight with a commercially manufactured model that was held in place by a set screw in the top of the sight. This made the removal and installation of the front sight easier, but if it is ever removed and reinstalled it tends to come loose when the carbine is fired. Front sights that are very difficult to remove, if not impossible, may have been cemented to the barrel by a previous owner. If you remove and replace the front sight, it is strongly recommended the set screw be treated with a thread lock substance that will hold it in place but not make it impossible to remove (e.g. Loctite Threadlocker Green)


Front sight set screw used mid 60's & later (first observed on s/n 338xx)

In September 1964 Universal Firearms Corp. and inventor, Abe Seiderman, applied for a patent for a 'Stock Lock Device'. This was a round barrel band for a newly designed M1 carbine stock. The stock tapered down at the forend, allowing the round barrel band to secure the handguard, barrel, and stock together. The band was secured to the stock using a set screw in the bottom of the band. Patent #3,208,178 issued September 1965. The first carbine utilizing this device was introduced in 1966.

A Change in Markings and Layout

By serial number 316xx Universal changed the markings and their layout on their carbines. The change was probably made sometime during 1964. This marking pattern continued into the 128000 serial number range with one change that eliminated a few letters.
The U.S. in 'U.S. CARBINE' was eliminated about s/n 87000.

Universal's Detachable Scope Mount

In October 1967 Universal Firearms Corp. and inventor Abe Seiderman, applied for a patent for a 'Detachable Mount for Telescopic Gun Sights'. Patent #3,424,420 issued January 1969. The left side of the receiver was drilled and tapped on most models after the scope mount was introduced. The stock was altered to accommodate the scope mount. When the mount was not in place, a soft piece of plastic snapped into the holes in the receiver and filled the gap between the receiver and the stock.

The scope mount holes, stock cut for the mount and plastic insert had become standard on all carbines manufactured by Universal Firearms during the Fall of 1964 (about s/n 41000).

Drilled & tapped receivers were standard on most models, once the mount was introduced.


The stock also came standard with a cutout for the scope mount. A piece of soft plastic was used to fill the gap when the
scope mount was not in use. Occasionally this plastic piece is lost. Replacements may be found at Numrich Gun Parts.

The First Catalog

Gun Digest 1967 shows the GI version of the Universal M1 carbine, with a footnote that Universal offered five other versions of their basic M1 carbine, including two models chambered for the .256 cartridge. Also shown is the Vulcan 440. A Universal Firearms Corp. advertisement from the 1960's is depicted in Ruth's War Baby Comes Home, p.738. It shows the GI carbine model with the GI type barrel band, and ten other models that all used the newly designed round barrel band and newly designed stock. The catalog, unfortunately, is undated. However, a catalog dated 1968/1969 shows a very different set of model numbers and offerings.

The model designations and carbines depicted in the following table are believed to be circa 1966 and prior.

The above carbines and those prior were built using many GI carbine parts. The number of companies using the surplus GI parts to build carbines eventually led to a shortage of GI parts in the later 1960's. As a particular part became unavailable, Universal manufactured or subcontracted for the manufacture of a replacement.

Expansion of Operations

In April 1966 Jack Seiderman, brother of Abe Seiderman, filed for incorporation of General Machine Products Manufacturing Co. 3675 E. 10th Court, Hialeah, Florida 33013. This location was almost right across the street from Universal Firearms and is believed to be one of the locations that manufactured parts for the Universal carbines. Tax records submitted beginning in May 1968 indicate Universal Firearms Corp. had expanded their main facility, using the address 3740-3746 E. 10th Ct., Hialeah, FL. This same year they added Paul Bines as Vice-President of Sales. Bines was head of sales when Shooting Times reviewed the Vulcan 440 in May 1965.

Part II: Universal Changes

Universal's Major Design Overhaul - Their M1 Carbine becomes the Universal Firearms Carbine

Introduction

As the availability of GI surplus parts dwindled commercial equivalents were manufactured. Several parts, such as the slide, were difficult to machine correctly. Commercial manufacturers began encountering a number of problems previously encountered by those who had initially designed and redesigned parts for the .30 caliber carbines during and after WWII. These issues were not specific to Universal Firearms and can be encountered by any company intent on making a functional replica of the U.S. carbines made during WWII. As with most firearms each design has it's strengths and weaknesses and the original carbine design was no exception.

Universal's solution to these problems was to significantly redesign their carbines. To a degree the end result should no longer be viewed as a replica of the U.S. .30 caliber carbine, Model M1. While similar in appearance and using the same cartridge the majority of their carbine and it's parts were no longer interchangeable with parts used with their earlier carbines, the replica carbines made by other manufacturers and the surplus GI parts for the original U.S. carbines.

This major change has been the cause of much criticism as Universal's hybrid has historically been compared to carbines of the design of the U.S. carbines. The change did create a number of minor problems Universal worked out over time. Of the 420,000+ carbines manufactured by Universal 1962-1984 over 350,000 of them were their hybrid version manufactured 1967-1984. If the hybrid design was flawed to the degree some have claimed no company would have survived this long making only their hybrid carbines.

Abe Seiderman, inventor of the design, authored a letter to customers giving an overview of some of the changes and why they were made. The letter may be viewed here: Comparing Virtues of Universal's .30 caliber Carbine to Others.

Carbine DesignSerial NumbersYearsQuantity Produced
Universal Firearms U.S. M1 Carbine Replicas: 2,000-99,999 1962-1967approx. 97,000
Universal Firearms Hybrid Carbine: 100,000 and up 1967-1984350,000+

One adverse effect of this design change didn't become an issue until several years after Universal was no longer in business. Replacement parts can sometimes be hard to find. As of 2017 most parts can still be obtained. A few of the parts are now manufactured by several different companies given the quantity of Universal hybrids still in use. Other parts can be obtained from various used parts dealers. These parts and their sources will be discussed throughout this text.

The Design

In September 1966 Universal Firearms Corp. and inventor Abe Seiderman, applied for a patent for a 'Combination Manual and Automatic Bolt Action for Firearm'. The title of the patent can be misleading, as the gas piston was just one small part of this overall significant redesign of the carbine manufactured by Universal. The patent was issued #3,382,766 in May 1968. Universal did not implement all of the design changes indicated in this patent at the same time. Most were included on the carbines manufactured by the late 1960's, some in the early 1970's.


Combination Manual and Automatic Bolt Action for Firearm Patent


Twin recoil springs, square gas chamber (Fig. 1 #21) heliarced to the barrel

The 'Combination Manual and Automatic Bolt Action' was a two piece gas piston (refer Fig. 4 #24 & #25, below) that was selectable for semi-automatic fire or single shots, requiring manual operation of the slide to extract the empty casing and chamber a live round. The pin in the gas housing goes through the forward half of the piston, securing both pieces. By removing the pin, the forward half of the piston can be rotated 180 degrees and pinned back in place, opening or closing the gas flow to select the mode of fire.

Universal's Recoil Slide, the Best Visible Clue as to What Lies Inside

Universal used GI or GI compatible slides up until the time they switched to the new design. The GI style slide has a handle that is solid. If you see a Universal carbine with a slide that has a solid handle, the gas system, recoil system, receiver, and barrel are the GI style with the one recoil spring.

The slide that Universal used to replace the GI style slide fits only Universal's redesigned carbine. This slide will not fit on any other carbine made by anyone else. It will also not fit on the Universal carbines that have the GI style gas and recoil system. This slide was specifically designed to work with the Universal two spring recoil system. There are variations to this Universal slide, but all of them have one obvious trait that makes them easy to identify. Universal cut the opening on the inside of the slide handle (that engages the bolt) all the way through the handle, making an obvious hole in the slide handle (Fig. 1 #7 above) for the bolt to engage.


GI slide with solid handle = GI type innards

Universal slide with hole in handle = Universal's redesigned innards

As mentioned above, Universal's modified slide with the hole for the bolt lug had several variations. If the need arises to replace this slide, it is important to know which of these variations your carbine uses. The variations are not interchangeable. Unlike the GI style slides, none of the newly designed Universal slides have any means to lock the slide/bolt open.

The Universal Firearms Set Screw Style Slide

In the photograph above left, close examination of the slide groove in the right side of the receiver reveals the GI style disassembly notch for removing the slide from the receiver (notch between the rear sight mount and bolt opening). Compare this to the receiver on the carbine in the photograph above right and you will see this disassembly notch is no longer present. The lack of this disassembly notch is also depicted in figure 1 of the patent.

This slide has a screw between the handle and the bolt opening. The diagram in the patent does not show this, however, the narrative on the first page of the patent text states the rear side of the slide has a channel parallel to the receiver channel that contains a 'fixed rectangular key' (Fig. 5 #18) that is inserted into the receiver groove from the rear when the slide is in place, slides forward under the slide, and is held in place between the slide groove and the receiver groove by a 'removable stop', which the text indicates is not shown in the diagram. This rectangular key guides the slide down the receiver groove. Loss of this small rectangular key, effectively makes the slide and bolt not function in semi-automatic mode.


'key' slides down receiver groove & under slide,
held in place by set screw

Underside of the slide showing a small groove, the key,
and the set screw that holds they key in place

To remove the slide from the receiver the screw is disengaged, allowing the rectangular key to slide out and be retrieved. The slide can then be removed from the receiver and disassembly continued. To reassemble the slide to the receiver, mount the slide on the receiver with the bolt lug inside the slide hole. Slide the rectangular key down the receiver groove and under the slide, leaving sufficient room for it to be secured by inserting the screw into the slide.

These slides have no mechanism by which to lock the slide back and bolt open.

The set screw style slide started at s/n 100,000 and was eliminated about s/n 109,000. It appears it was used less than a year.

The Universal Notch Style Slides

Starting at about s/n 109,9xx the slide was redesigned replacing the screw and key with an integral protrusion that slid back and forth down the slide groove in the receiver, similar to the GI style slide. A slide disassembly notch was added to the Universal receivers. The slide is removed in the same manner as a GI style slide. This slide was used until the end of production.

These slides have no mechanism by which to lock the slide back and bolt open.


Slide key & set screw replaced by a slide disassembly notch in the receiver and a
permanent fixed protrusion that guided the slide along the groove in the receiver.

A change in barrel design resulted in two different versions of this slide. One was designed to fit barrels that were round on the sides, the other to fit barrels that were squared and flat along the sides.

Final Change to the Universal Markings & their Layout

About 1968 Universal made one final change to the markings they used on their carbines and where they were located. These markings remained unchanged throughout the rest of Universal's existence. The change did not take place at a particular serial number. Use was sporadic starting at s/n 125,000. It became the standard by s/n 129,000.

A New Set of Model Numbers

Universal had two basic sets of model numbers, none of which were indicated on the actual carbines. Carbines manufactured and sold in the early and mid 1960's had one set of model numbers (see above). Carbines manufactured and sold 1968 and later used a different set of model numbers. Not all of the carbines in the second sequence appeared at the same time. Model numbers were added and dropped between 1968 and 1988 as the different styles and variations were introduced or dropped from Universal's line.

Presenting these model numbers piecemeal as they came and went easily causes confusion. For this reason all of the model numbers 1968-1988 appear in the one chart below. The source for each model is one or more original Universal catalogs between 1968 and 1980, referenced in the far right column and detailed at the bottom of the chart. Part III of this text provides photographs and more detailed information on specific models.

Universal Carbine Serial Numbers

M1 Universal Carbine Serial Numbers

The Vulcan slide action .44 magnum carbine was apparently discontinued before the publication of the catalog for 1969-1970.

The download for the Owner's Manual used 1978-1983 is available at 'Maxicon.com'. Maxicon includes further information on the Universal carbines, including an accessories catalog from the late 1970's.

Changes & Dark Days
1969-1972

Universal Container Corporation and Mondex Inc.

Early in 1969 Universal Firearms was purchased by Universal Container Corporation, a division of Mondex Inc., an investment corporation with publicly traded stock. Abe Seiderman was retained under contract to operate the manufacturing plant. Mondex Inc. of Madison Ave. in New York City invested in a variety of businesses in Florida during the same time period with most having to do with real estate.

In May 1969 Universal Firearms Corporation notified Florida they had changed the company name to Universal Sporting Goods 3740-3746 E. 10th Ct, Hialeah, FL. Yearly corporate tax forms beginning September 1970 identify the company as Universal Sporting Goods Inc. at the same address. The corporate tax form submitted in November 1970 identifies Seymour Sommerstein as President, Robert Sommerstein Vice-President, Paul Bines Vice-President of Sales, with Abe Seiderman as Vice-President of Manufacturing and Secretary. Four Mondex employees were added to management. Warren Trilling of New York City as Treasurer, Lee Ledford of New York City as Asst. Secretary along with two new Directors.

The name 'Universal Firearms Corp.' remained on the catalogs, boxes, and user manuals.

Changes

Management at Universal Container Corp. implemented a number of changes in the manufacture of the Universal Firearms carbines that were likely intended to reduce overhead costs and increase their profits. The changes included the use of cast parts with improper hardening of both cast parts and parts milled from forged steel. Seiderman wrote letters to the decision makers explaining why the changes should not be made. Their final decisions prompted Seiderman to refuse to work in the same building with them.

In December of 1970 Paul Bines filed for incorporation of Dynamic Merchandise at 13004 SW 87th Ave in Miami with Bines as President, Abe Seiderman as Vice-President and their wives as corporate officers. The articles of incorporation for Dynamic Merchandise state the business would be what the name describes, a dynamic merchandiser. The records say nothing about firearms.

Seiderman was still under contract to Universal Container Corp. but operated from the 87th Ave. building of Dynamic Merchandise as Universal's VP of Mfg and Secretary from a distance. Seiderman and Bines started retail sales from this location selling Universal carbines concurrent to the carbines being sold and shipped by Universal Container Corp. from the Universal Firearms facility. Seiderman modified the Universal Firearms carbines he sold to correct what he viewed as deficiencies in the changes made by Universal Container Corp.

Examples from Changes Implemented by Universal Container Corp. 1969-1972

To keep things in perspective, the photographs that follow are 3 of approximately 70,000-80,000 carbines manufactured between 1969 and 1972. Not all of the carbines made during this time had these issues.

We do not know the first serial number after Universal Container Corp. took control of Universal Firearms, the serial numbers of the carbines when changes were made the changes made. As you will read below we do know these issues stopped when Seiderman bought the company in 1975 with Seiderman starting his serial numbers at 300,000 to separate the carbines he made from those made under the management of Universal Container Corp.

Serial numbers between approx. 130,000 and 299,999
If you own a Universal Firearms .30 caliber Carbine within this serial number block it is strongly recommended you examine and continue to examine the barrel in the area of the gas piston for any damage to the barrel. If you find even a small amount of damage do not fire the weapon. Any doubts whatsoever should be addressed by examination of the carbine by a competent gunsmith. Keep in mind these particular carbines are also now over 40 years old and well used firearms.

Understanding a Few Basic Concepts
The position, angle and diameter of the hole in the barrel known as the gas port is critical to the operation of the carbine. Likewise the dimensions of the interior of the gas piston housing/cylinder, the dimensions and weight of the gas piston, the distance the gas piston travels and a number of other factors are also critical not only to the function of the carbine but also to the safety when firing the carbine. Altering any of these can create a snowball affect on everything that depends on the proper operation of these parts. The photographs that follow are a good example of this.

Universal Firearms .30 caliber Carbine s/n 165165

The indentation in the barrel below made by the gas piston could have been caused by one or more of a number of things.
Examples include improper hardening of the barrel or gas piston. An oversized or undersized gas port creating higher
pressure within the gas chamber. Whatever the cause if you see damage to the barrel from the gas piston the weapon
should not be fired and examined by a gunsmith,



Universal Firearms .30 caliber Carbine s/n 173297

The owner of this carbine saw the damage as seen above.
Then decided to give the gas piston more room to operate.



On his next trip to the range he exercised caution with distance. On firing the gas piston housing separated from the barrel.
Fortunately the slide absorbed most of the impact preventing the gas piston housing from penetrating the stock. There were
no injuries but the damage made this carbine scrap for parts. Note the size of the gas port hole. It appears too large
but the dimensions of the gas chamber it fed into and the gas piston it operated also figure into the equation.


Universal Firearms .30 caliber Carbine s/n 179907

This carbine is a good example of not having enough information to draw any conclusions as to the cause.
Most would assume the weld securing the gas housing to the barrel failed. The question may be why
did the weld fail? After seeing the two carbines above what do you think?


Important Lessons to Pay Attention Too...

(1) Maintain, inspect and respect your firearms. Leave repairs to those qualified to do them. Hospital bills are rarely less expensive than a gunsmith.

(2) ALL commercial firearms sold for civilian use have been and still are built by companies we rely on to exercise due diligence in manufacturing a safe firearm. Every single one of these companies needs to make a profit to survive. Most all go through financial good times and bad times. Most maintain due diligence in making a safe firearm. A few don't. As in this case, a few get bought by investors who make decisions that can cause injuries and/or destroy a brand name.

(3) The timing of the investors and their decisions in relation to Universal's change to a hybrid carbine design has been a strong contributing factor to a never ending bad reputation not only to the brand name but also to the hybrid design. The hybrid design garnered criticism for a number of reasons especially with collectors and owners of the U.S. .30 caliber Carbines manufactured under contract to Ordnance during WWII. While it used the same ammunition and retained a resemblance the hybrid was no longer an M1 Carbine. Different doesn't necessarily mean better or worse. It means different.

Keep in mind Universal existed from 1962-1984 manufacturing over 480,000 carbines. Over 350,000 of their carbines were their hybrid design. Manufactured for many years after the carbines shown above.

(4) Every part on every gun has a lifespan. Universal hasn't made a carbine since 1984. Their carbines are no longer Universal carbines as much as they are a used firearm. A 'jam', 'misfeed', catastrophic failure and much more may have nothing to do with who made it and everything to do with who used it, and possibly abused it, over the years. See (1) above.

So the history continued ....

Universal adds a Unique Slide Lock to hold the Bolt Open and Changes their Bolt

In the early 1970's about s/n 185500 Universal introduced a lever on the right side of the receiver to hold the slide back and bolt open. This change became their standard by s/n 198000. The lever had a small round ball on top to enhance leverage and grip. The ball was eliminated towards the end of production at about s/n 470000 leaving a straight pin lever. A word of caution: DO NOT remove the ball, lever or opposite end inside the receiver. They can easily become lost while experiencing a fair amount of frustration trying to get them back into the receiver. Replacements are virtually non-existent.


Lever for locking slide back & bolt open


Rotating the lever allows the extension inside the receiver to
engage a notch in the bolt to hold the slide back and bolt open.

At the same time the bolt hold open mechanism was added Universal changed the design of their bolts. Bolts used prior to this change were based on the GI design of a floating firing pin. The firing pin of the GI design has a tang at the rear that engaged a slot milled in the receiver bridge to hold the firing pin in the rear of the bolt until the bolt had fully rotated and locked. As with most firing pin designs the floating firing pins have strengths and weaknesses. The design has been commonly used in military weapons given the use and environment for which they are intended.

The change implemented by Universal eliminated the tang on the back of the firing pin and the need for proper machining of the receiver bridge that engaged the tang. The proper machining of this bridge has been a challenge for most all commercial manufacturers since their beginning. One of the common negative comments about the Universal carbines is this change eliminated one of two safety designs that prevent the firing pin from striking the primer before the bolt has fully rotated and locked. The change didn't eliminate this safety feature, it simply changed the design to a different design commonly used in semi-automatic firearms to hold the firing pin in the rear of the bolt until struck by the hammer. As with the floating firing pin design this design also has it's strengths and weaknesses but has long been accepted as a safe means of accomplishing the same goal.

Abe Seiderman, inventor of the design change, authored a letter explaining the changes and why they were made. The letter may be viewed here: G.I. Type Tang Firing Pin.

These changes further distanced the Universal carbines from the design of the U.S. carbines but enhanced the abilities of the Universal carbine hybrid. The downside is this change eliminated compatibility with the GI bolts or bolts made to GI specifications. Universal carbines having the slide lock lever are not compatible with any bolt other than those made by Universal as a result of this change.

Abe Seiderman Takes Over
1975, Serial Number 300,000

In June 1974 Universal Sporting Goods filed a change of address with Florida, indicating a new address of 7920 NW 76th Ave., Medley, FL (part of Miami). Employees of Mondex Inc. became the president, vice-president, and directors. The State of Florida Division of Corporations records show Dynamic Merchandise Inc. relocated to 3740 E. 10th Court, Hialeah, FL 33013 (Universal Firearms facility) in May of 1975.

In 1978 Abe Seiderman authored a notice that went out to many different distributors and customers due to the damage caused to the Universal Firearms brand name with the carbines built under Universal Container Corp. 1969-1972. This notice addressed the issues that had been corrected and provides a glimpse into the company's history during this time period.

The U.S. Patent Office and Florida patent records indicate in February 1976 'Dynamic Merchandise dba Universal Firearms Incorporated' applied for, and obtained, a trademark for the name 'Universal Firearms'.

It appears Universal Container Corp. and Mondex didn't voluntarily walk away from Universal Firearms. In October 1978 Mondex Inc. incorporated 'Universal Firearms, Inc.' at 8397 NE Second Ave. in Miami. This corporation was voluntarily dissolved 7 months later by Mondex in May 1979. In December 1979 Universal Sporting Goods notified Florida their corporation had been dissolved.

About the time of the dissolution of Universal Sporting Goods, the name 'Universal Firearms Corp.' again appeared on their catalogs, boxes, owner's manuals, etc. However, the name and address on these items was changed to Dynamic Merchandise 3740 E. 10th Court, Hialeah, FL 33013. The Universal Firearms logo was changed to the one depicted above with the link to Seiderman's notice.

A side note. Seymour Sommerstein no longer appeared in the records affiliated with any of these companies after 1973. In January 1974 Sommerstein incorporated Armsport Inc. at 3590 NW 49th ST., Miami FL 33142. Armsport was a major importer of firearms, many of which were manufactured in Italy. Armsport Inc. was dissolved in January 2007.

A .22 long rifle Conversion Kit, and a new Carbine Model

In April 1978 Universal Firearms Corp. and inventor Abe Seiderman, applied for a patent for a 'Conversion Kit for Semiautomatic carbines'. This was for converting an M1 carbine to .22 caliber by replacing key components making the carbine a straight blowback gas operated .22 caliber M1 carbine. The patent was issued September 1980 Patent #4,220,071.
