The machining (or lack there of) around the oprod track in the receiver shows some of the issues these rifles had with their cast receivers, but overall if it runs and you are happy it probably doesn't matter much. It might have a shorter life than say a better quality LRB receiver but at the price you paid who's going to complain?
For example, Federal Ordnance M14SA serial number 502XX was assembled at the factory on September 13, 1991 with Chinese manufacture bolt, operating rod, firing mechanism and barrel. Chinese and Taiwanese M14 parts were purchased from U. Receivers with serial numbers above 60XXX have engraved heel markings. USGI parts and bolts were used extensively in Federal Ordnance rifles through at least serial number 88XX.36 In 1989 Federal Ordnance renamed the rifle the M14SA and M14CSA. Rifles in the 93XX serial range and higher utilized modified receivers designed to accept Chinese-made bolts, barrels, and other parts owing to a shortage of original. The receivers were marked Federal Ordnance and are duplicates on the serial numbers in the 50,000 range except for the 3 digit serial number. It is not known if these three digit receivers were given serial numbers by Federal Ordnance as opposed to Sarco.
I had one years ago, it was a decent shooter and was made from mostly USGI parts, later I heard they switched to Chinese but still as a good shooting representation of a M14 they do OK. For $600 the parts are worth that. These Federal Ordnance rifles are an interesting chapter in M1A production. The following is excerpted from From M14 Rifle History and Development Fifth Edition by Lee Emerson copyright 2012:'.Federal Ordnance began production of its M14 type rifles by 1984 and ended in late 1991.
Federal Ordnance was not able to compete with the price of imported Chinese M14 rifles so production was halted. After the first fifty, M14 receivers were machined on one CNC machining center with several fixture set ups. All receivers were machined from castings of AISI 8620 alloy steel. Except for the first fifty receivers, the castings were supplied by Electro Crisol Metal, S.A. The M14 receivers were manufactured at a leased building one block up on Potrero Avenue.
Heat treating was subcontracted to a vendor in El Monte, CA. Federal Ordnance M14 type receivers were heat treated and carburized according to USGI drawing F7790189. A company in Santa Ana, CA finished the receivers with a phosphate coating. Assembly of the Federal Ordnance M14 rifles was performed at a leased warehouse just west of 1443 Potrero Avenue.
Each M14 was proof fired before assembly and function tested with three rounds as a complete rifle before packaging. Finished M14 rifles were stored on the first floor at 1443 Potrero Avenue.
The total number of complete M14 rifles assembled by Federal Ordnance was more than 13,000. Based on information available, total M14 receiver production did not exceed 16,000.The Manufacturer's Suggested Retail Price for a Federal Ordnance M14A in 1988 was $629.00 and its M14SA listed for $700.00 in 1991.
The rifles were sold with a one year parts and labor warranty. Each Federal Ordnance M14 type rifle sold was accompanied by a factory inspection tag, warranty registration card, a copy of U.
Army FM 23-8 and a fourteen page booklet on firearms safety and care. The safety booklet was written by Federal Ordnance, Inc.
The factory inspection tag included the following information about each rifle: date, stock number, a description, caliber, and signature fields for checking of headspace, test firing and inspection. USGI M14 accessories such as magazines, magazine pouches, slings and cleaning kits were available from Federal Ordnance.Federal Ordnance built two types of M14 rifles, one with USGI parts and one with Chinese parts. Model numbers M14 and M14A were designed to accept USGI bolts and barrels. Otherwise, the receiver was manufactured to mate with Chinese bolts and barrels.
Federal Ordnance M14 Serial Number Dates
USGI parts were used extensively in Federal Ordnance rifles through at least serial number 8877. The USGI parts were taken off USGI M14 rifles imported from Israel. By serial number 9279, if not earlier, Chinese and Taiwanese reproduction parts were used to assemble its rifles. For example, Federal Ordnance M14SA serial number 502XX was assembled at the factory on September 13, 1991 with Chinese manufacture bolt, operating rod, firing mechanism and barrel. Chinese and Taiwanese M14 parts were purchased from U. Receivers with serial numbers above 60XXX have engraved heel markings.
The model number changed from M14A to M14SA between serial numbers 9139 and 9279. Four digit serial number Federal Ordnance receivers observed were marked on the side with the letter F inside a circle. This marking was sometimes lightly stamped. The circle F marking has not been observed on serial numbers above 10000. Federal Ordnance sold complete rifles as well as stripped receivers. Federal Ordnance sold a few M14 rifles to walk-in retail customers and through Shotgun News advertisements but most were sold to firearms distributors.Some fiberglass stocks on Federal Ordnance M14 rifles appear to have been commercial manufacture of unknown origin.
The original owner of Federal Ordnance M14SA serial number 22XX reported that the synthetic stock never had a selector cutout or USGI markings inside the magazine well. Further, the Federal Ordnance stock had a slightly rough finish. The butt plate was glossy black color instead of phosphate coated.
Federal Ordnance M14 rifles were also sold with refinished wood, new walnut and USGI synthetic stocks. This is an interesting observation from the Fulton Armory Website - from their reciever page:As to strength: Why did Fulton Armory select machining from a casting as our method?About 10 years ago a customer sent in a Federal Ordnance M14 that had “blown up” for us to perform a tech inspection. Shooter was okay.
Federal Ordnance, now defunct, produced thousands of a very poor quality receivers (poor geometry, but good material & good heat treat), that was machined from a casting and had digested one of those infamous CBC 75.308 cartridges that produces “in excess of 140,000 copper units” of chamber pressure (nominal is 50,000). This CBC 75 ammo blew up, and continues to blow up, any and every rifle that see’s that 140,000 CUP. Here’s the interesting part: The receiver held.
There was a partial crack in the receiver below the right locking lug of the receiver, but it did not detach or fail. The locking lugs of the receiver were untouched, the locking lugs of the TRW bolt had been impressed into the receiver’s lugs by something like 10,000ths of an inch; huge depressions in both the right & left bolt lugs. The bolt held. The barrel was in perfect shape. So, what “blew up”?
The case failed, released the gasses into the mag well, peeled the bottom of the bolt away, inflated the magazine and blew the stock apart. A poorly machined cast receiver, even with poor geometry, but with proper heat treat & proper material, is vastly stronger than the rest of the system.About 20 years ago we inspected an original USGI forged M14 receiver that had blown apart into 4 pieces on the firing line at The National Matches, Camp Perry, OH. Shooter was knocked out, but fine otherwise. So, why did the USGI M14 blow apart in 4 pieces? Bad receiver? No (good geometry, good material, good heat treat). No (issue LC).
Bad assembly techniques? No (well built rifle). The barrel failed due to bad lot of steel. The heavy match barrel had split from the chamber mouth down to the heavy oversize op rod guide. When the barrel split open wide at the receiver ring it introduced lateral forces to the receiver ring, and split it apart like an axe splitting firewood. M14 receiver rings are not designed to take chamber pressures nor lateral forces, no matter how they are made.These, and many other failures over the decades demonstrated to us, in a very hands on way, the same thing Col. Hatcher found in his destructive testing of the M1 Garand receiver: That J.C.
Garand’s receiver design is so remarkably strong that inevitably some other part of the rifle system will fail long before the receiver, providing it has good geometry, good material and good heat treat. Cast, forged or billet.So, to keep the receiver costs affordable for all of our customers, we chose to cast & machine, while spending a whole lot of time and care in assuring the quality of the machined geometries, correct 8620 alloy steel, and proper heat treat for case & core.
Federal Ordnance M14 Serial Numbers For Sale
The finest M14 receiver available, at any price. I used to be a regular customer at Fed Ord in El Monte in the 1980s.
I had a friend there in the armorers shop and he kept me clued in on good deals. Most of the M14 clones were good but occasionally some of them as well as some of their rebuild Garands, like their tankers and BM59s had loose threads in the receivers due to mismatching barrels with them. Look for silver solder edges to see if they locked them in since they were not torque tight. He rebuilt me a Broomhandle with a 9mm barrel and it worked great. By the pictures this is a good one.

The Founding of Federal Ordnance
In the early 1950's Burton 'Bob' Brenner became associated with Martin B. Retting at Retting's gun store in upstate New York. In the mid 1950's Retting sold the gun store to George Numrich and moved to the Los Angeles area with Brenner and started Martin B. Retting in Culver City, CA. Over time Numrich and the company's subsequent CEO, Gregory Jenks, expanded the upstate New York operation into what is known today as Numrich Gun Parts of West Hurley, NY (E Gun Parts, Gun Parts Inc., Numrich Arms).
In The American Rifleman issue of July 1957, a three page advertisement announced Martin B. Retting was merging with Golden State Arms in Pasadena, CA. Golden State Arms is covered in more detail on this website under the name of Santa Fe. Within two years Retting separated from Golden State Arms and remained with his business in Culver City, CA. Brenner remained with Golden State Arms. In the Independent Star News of Pasadena, CA, August 16, 1959 an article on Golden State Arms identifies Burton Brenner as the youngest of three partners, the others being the founder Alvin Gettler, and Seymour Ziebert. For further on Martin B. Retting, refer to the pages on Santa Fe and National Ordnance M1 carbines.
Gettler left Golden State Arms in 1960 [Star News of Pasadena, CA May 6, 1965]. Ziebert and Brenner ran the business until financial difficulties caused the business to be auctioned in November 1966 [Long Beach Press Telegram, October 30, 1966 p.C4]. Ziebert moved to Spain and on November 16, 1966, Brenner founded and incorporated Federal Ordnance at a post office box in Los Angeles.
Federal Ordnance's affiliation with National Ordnance
While employed at Golden State Arms Brenner had met John Arnold. In 1960 Arnold ran Alpine Industries, the distributor for National Ordnance M1 Carbines. Robert E. Penney Jr. handled the operational end of National Ordnance in Azusa, CA. In the Fall of 1962 Arnold took over the National Ordnance M1 Carbine operation and moved to South El Monte. Penney took the Alpine name and moved to another facility in Azusa where he manufactured M1 Carbines marked with the Alpine name. In addition to the National Ordnance M1 Carbines, Arnold assembled and sold Springfield 1903A3 rifles. Arnold had an ongoing need for surplus GI 1903A3 rifle parts.
When Brenner left Golden State Arms he was in possession of a large quantity of Springfield 1903A3 parts. Shortly after he founded Federal Ordnance Brenner met with Arnold and reached an agreement whereby Arnold would manage assembly and sales of the rifles being manufactured by National Ordnance, and Brenner as Federal Ordnance would manage parts acquisitions for National Ordnance. In 1967 Brenner and Federal Ordnance moved in with Arnold and National Ordnance at 9643 Alpaca in So. El Monte. Brenner related the two companies were maintained as two separate companies cooperating with one another. Brenner enjoyed traveling the world making deals with various countries and companies for parts and ammunition. Parts that could be used by National Ordnance were transferred to Arnold, ammunition and parts not needed by Arnold were sold by Federal Ordnance.
In 1968 Ilia and Jack Karnes opened A.R. Sales at 9624 Alpaca in So. El Monte, several buildings west and across the street from National Ordnance and Federal Ordnance. A.R. Sales manufactured Model 1911 receivers using aluminum. Karnes had worked for Golden State Arms under Ziebert and Brenner, managing a warehouse and assembly facility in Puerto Rico, where he had met his wife Ilia. In 1958 Golden State Arms had published a book on firearms, World's Guns and other Weapons. Brenner was the Executive Editor, Karnes was an Associate Editor. A.R. Sales operation was initially a Karnes operation and not involved with Brenner, Arnold, or their companies. Karnes was often visited and/or consulted by Arnold, Brenner, Bob Penney and their employees. Karnes was known and respected for his old school machinist skills.
Federal Ordnance Moves, next door to National Ordnance
In 1969 construction was completed on a new 3200 sq. ft. building next to National Ordnance. National Ordnance remained at 9643 Alpaca, Brenner and Federal Ordnance moved into the new building just east of National Ordnance at 9647 Alpaca [Los Angeles County Tax Assessors Office].

Federal Ordnance absorbs National Ordnance
In 1973 John Arnold died of cancer. His will, the original having been read by this author, left National Ordnance to Jessie LaMont, wife of Wyant LaMont (manager of National Ordnance), and Walter Rayno (shop manager at National Ordnance).
The disposition of National Ordnance and reorganization of operations, personnel, and machines under Federal Ordnance required a number of years. Brenner had no experience at running the manufacturing and/or assembly end of the business. In June 1975 Brenner arranged for the shop manager of National Ordnance, Walter Rayno, to run the shop at Federal Ordnance. The following weekend Rayno died of a heart attack. Shortly thereafter, Jessie LaMont and Rayno's wife sold National Ordnance's assets to Bob Brenner. What Brenner couldn't use he sold to Sarco Inc. in Sterling, NJ, a major gun parts wholesaler and retailer.
Brenner hired Jack Karnes of A.R. Sales as his chief machinist and eventually purchased A.R. Sales along with it's machinery and 1911 inventory. Brenner renamed the business Ranger Machine & Tool Corporation, which he incorporated in May 1981. Initially the business remained in the same building at 9624 Alpaca. Jack Karnes stayed on as Brenner's chief machinist for both Federal Ordnance and Ranger Machine & Tool.
In 1981 Brenner relocated Federal Ordnance approximately 1 mile southeast to a 10,080 sq. ft. warehouse at 1443 Potrero in So. El Monte. The smaller warehouse at 9649 Alpaca was retained as a machine shop.

U.S. M1 Carbine Receivers from the Philippines, imported by Federal Ordnance
Sometime in the mid 1980's Brenner negotiated the purchase of a large quantity of M1 Garand parts from the Philippines. When the parts arrived in South El Monte and were sorted they discovered one crate containing approximately 300 U.S. M1 Carbine receivers. Brenner related he sold almost all of the receivers to Sarco in Stirling, NJ. These were not manufactured by Federal Ordnance. They were U.S. GI receivers manufactured during WWII and retain their original manufacture names. The Federal Ordnance name and So. El Monte, CA are an importer's marking, required by U.S. law since the Gun Control Act of 1968.
Records of the U.S. Military Assistance Program maintained by the National Archives indicate the Philippines received 8831 U.S. M1/M2 Carbines between 1950 and 1963.
Inland U.S. M1 Carbine with Federal Ordnance Import Mark. Imported from the Philippines in the mid 1980's.
Brenner indicated the receivers were intact (not cut/demilled) but were extremely dirty, with some having heavy pitting.
Sarco sold the receivers retail for owners to build their own carbines. Examination of carbines having these receivers has revealed some of them have been repaired by welding (broken rear lug that engages trigger housing), but none so far appear to have been two M1 Carbine receiver pieces welded into one.
The M1 Carbines Manufactured by Federal Ordnance
Prior to the interviews with Brenner one of his ex-employees, Robert Thomasser, had related to this author he was hired as a machinist at Federal Ordnance in 1982 to work on the Federal Ordnance M14's. Thomasser indicated he did not work on the M1 Carbines or M1 Garands. Carbines were being worked on by Karnes when Thomasser was hired. Thomasser related the receivers for the M1 Carbines and M1 Garands were cast by ECRIMESA in Santander, Spain. At the time of the interview in August 2008 Thomasser owned and operated Pacific Canvas & Leather in Phelan, CA. Jack Karnes passed away in Los Angeles County in May 2008.
In their last few years of existence National Ordnance contracted Electro Crisol Metal, S.A. (ECRIMESA) in Santander, Spain to cast M1 Carbine, M14, and several other receivers. Ecrimesa is a very large well known metal foundry with a long history in manufacturing firearms. Several sources have indicated all of the M14, 1903A3, and M1 Garand receivers used by Federal Ordnance were cast by Ecrimesa. It's highly likely Federal Ordnance obtained their M1 Carbine receivers from Ecrimesa. An ongoing effort is underway to locate one of the National Ordnance receivers made in Spain to closely examine the evidence left the tooling used to cast it (refer to National Ordnance for further). Contact with Ecrimesa via several different avenues so far has met with no response.
Bob Brenner of Federal Ordnance purchased the remains of National Ordnance from the families of two National Ordnance personnel who inherited it on the death of it's owner in 1974. Brenner sold some of the National Ordnance inventory to SARCO about 1976, including the old tooling and dies used by National Ordnance for their M1 Carbines from 1960 through approximately 1971 (segmented recoil spring hole), prior to the receivers made by Ecrimesa..
The tooling used to manufacture the Iver Johnson carbines from 1979 through 1982 matches the casting mold marks that appear on the carbine receivers used by Federal Ordnance 1982 and later.
Most of the commercial companies who made M1 Carbines had possession of, or access to, surplus carbine parts. They would acquire receivers and barrels with which to build M1 Carbines. This appears to have been the case with Federal Ordnance.
The best evidence as to what was done at Federal Ordnance relative to the M1 Carbines that have their name have been the actual carbines. Hopefully owners will share additional information that will assist with what has been observed so far.
Serial Numbers
Serial numbers used by Federal Ordnance that have been observed so far fall into one of three different serial number blocks.
FEDERAL ORDNANCE M1 CARBINE RECEIVER SERIAL NUMBERS (rounded to the nearest tenth) | |||
Year Manufactured | Lowest Observed (so far) | Highest Observed (so far) | Differences |
1984 | 40,003 | 40,851 | Receiver #1 (below) |
1985-1986 | 50,960 | 51,820 | Receiver #2 (below) |
unk | 24 | 0240 | Receiver #2 (below) |
Five digit serial numbers starting with a 4 were assembled in 1984. The first number was changed to a 5 for 1985 with the four numbers that followed being a continuation of the serial number sequence started in 1984. Advertisements and sales continued into 1986 but it is not known if production ended in 1985 or continued into 1986 without changing the 5 to a 6. The characteristics of the markings on the receivers having two or three digit serial numbers have been consistent with those with serial numbers begin with 5.
Use of the encircled F (a Federal Ordnance logo) preceding a serial number appears to have started sometime between serial numbers 51100 and 51600 but isn't always present with the higher serial numbers.
Federal Ordnance M14 Serial Numbers
The July 1, 1985 issue of Shotgun News carried a Federal Ordnance advertisement that offered M1 Carbine receivers for sale indicating they were made from 8160 steel.
Receiver #1: S/N Sequence 40,000 (1984)
This receiver was cast using the tooling and dies used by Iver Johnson's Arms in Middlesex, NJ for their carbines they manufactured from 1978-1982. In 1982 Iver Johnson was bought by a group of investors in Arkansas who moved the company to Jacksonville, AR. The Arkansas operation inherited a number of receivers in various stages of machining from the New Jersey operation. Some of these receivers they used but eventually switched to a different tooling and mold than was used by Iver Johnson in New Jersey.
Federal Ordnance may have bought these receivers from Iver Johnson's Arms, acquired them from someone else who purchased them as surplus, or had them cast from the tooling and mold used by Iver Johnson's Arms in New Jersey 1978-1983.
Then encircled F has not appeared on the receivers in the 40,000 serial number block.
Note the curve on the front of the lug the trigger housing pins too
Note the casting mold lines
Receiver #2: Serial Number Sequence 50,000 (1985) & Three Digits Serial Numbers
This carbine was built using surplus GI parts with a commercially cast receiver. As with the 40,000 series, this barrel was constructed using the gas piston housing and rear half of a GI carbine barrel (in this case, an Inland barrel) into which was inserted a machined down 1903 barrel. The receiver casting mold lines match the receiver in example #1 above.
The name plate used for the U.S. Carbine Cal. 30 markings to be cast was different than the one used in example #1. The spacing of the letters and alignment are different. Instead of CAL 30 M1 the markings are CAL 30 ML. The reason for the change of the 1 to the letter L is an unknown. The change may have initially been unintentional but use of ML continued throughout the rest of the Federal Ordnance carbine production as well as being inherited and used by Israel Arms International, Auto Ordnance, and the commercial company who adopted the name of Inland Manufacturing. Inherited by using Lamothermic Precision Investment Casting in Brewster, NY, the casting foundry in possession of the receiver casting dies.
Example #2 also differs from the example above as the Federal Ordnance name and location was also cast with the receiver by use of a name plate in the receiver mold.
These changes appear to have taken place early during the 50,000 serial number block starting with the use of engraving to apply the Federal Ordnance name and location. Followed shortly thereafter by the change of the M1 markings to ML along with the casting of the Federal Ordnance name and location as shown in the example below.
Note the ML instead of M1

The circled F is not part of the serial number, was not used numerically, and often not present.

Federal Ordnance Changes Faces and Passes into History
Federal Civil Court records show on August 27, 1998 Briklee Trading, Burton Brenner, and Richard Siegal were sued for breach of contract by Beyton Ltd. Beyton Ltd was an off shore corporation located on the Isle of Jersey (off the coast of France), with a physical address in Luxembourg. The suit was filed in the United States, the case was heard in U.S. Federal Court in Los Angeles [2:98-cv-07040-CBM-CW Beyton Ltd v. Briklee Trading Co, et al]. The court records indicate Burton Brenner and Richard Siegel were Briklee Trading. The outcome of the suit in 2000 caused Siegel to file for Chapter 7 Bankruptcy. Brenner retained Briklee Trading, but the company was no longer doing business.
Shortly after the above lawsuit was filed, on November 3, 1998 Brenner incorporated Pacific Ordnance in California. The business was located in Pico Rivera, CA, and sold a small line of shooting accessories and a few items left over from Federal Ordnance.
In 2002 Brenner suffered a stroke that left him unable to continue operating the business and caused him to file for bankruptcy. Brenner never fully recovered from the stroke and passed away in August 2009 in Sherman Oaks, CA.
Surplus M1 Carbine Receivers left over from Federal Ordnance
Fed Ord M14 For Sale
According to Larry Horner (Liberty Armory) who was hired by Israel Arms International (IAI) in 1995 to assemble their carbines, the first IAI carbines were assembled using surplus Federal Ordnance receivers. The first receivers used by IAI match Federal Ordnance Receiver #1. They were followed by receivers marked Made in Spain. Examination of the first receivers used by IAI revealed the same casting mold marks as those observed on the Federal Ordnance carbines (refer to the pages on IAI for further details).Few of the three digit serial numbers have been reported to date. Some of these were sold as receivers only by Sarco in 2007, over 14 years after the demise of Federal Ordnance. Sarco specializes in acquiring and selling surplus some of which is obtained from companies who are at the end of their lifespan or from auction houses selling the leftovers of these companies. The receivers were marked Federal Ordnance and are duplicates on the serial numbers in the 50,000 range except for the 3 digit serial number. It is not known if these three digit receivers were given serial numbers by Federal Ordnance as opposed to Sarco.
Other Weapons from Federal Ordnance
When the complete firearm could not be imported, Federal Ordnance would import the parts and arrange for the receiver to be manufactured. Receivers were normally made by investment casting. Federal Ordnance then built the complete firearm using the parts and the cast receiver.
One example of this are the Federal Ordnance M14 rifles. The M14 is a selective fire weapon, capable of fully automatic fire. The People's Republic of China had manufactured copycats of the U.S. M14 and had made them available for sale as exports. Federal Ordnance, as did other companies, imported the parts off the Chinese M14's. Federal Ordnance arranged for the manufacture of semi-automatic only M14 receivers, on which were built the entire rifle. For further information on the M14's, including those manufactured by Federal Ordnance.
Please note, my research has been the M1 Carbines. I have little to no information on all the other weapons they imported and/or made other than what is shown here.Federal Ordnance M14 Price Range
