Forgotten Weapons
Published 24 Sept 2025Prior to 1986, Group Industries imported BAR parts kits and then manufactured and registered full-auto receivers for them. This produced transferrable guns which were subject to NFA registration and the $200 transfer tax — which was a much more significant sum at that time than it is today. Some of the potential customers were people (like reenactors) who wanted guns that looked and handled like real BARs but were not regulated by the NFA. To satisfy this subgroup of customers, Group designed a receiver which neither had nor could be adapted to have a gas piston, rendering the gun manually operated. It would fire from an open bolt, but had to be manually recocked after each shot. This was not legally a machine gun, and he made 68 of them.
When the Hughes Amendment to the FOPA passed in 1986, manufacture of new transferrable machine guns ceased, and Group Industries went out of business. Its assets were sold off, including a number of parts kits and unbuilt M.O.R. receivers. One of the buyers was Ohio Ordnance Works (then called Collector’s Corner). They got ten receivers and after selling them, decided to develop a semiautomatic BAR for that same non-NFA BAR market. That gun ended up being the M1918A3, which is still available from them today.

FAMAS G1: Simplified for Export
Forgotten Weapons
Published 17 Sept 2025The FAMAS G1 was developed as a lower-cost option for FAMAS export sales. The original F1 model had been offered for international sale, but it attracted little interest largely because of its high price. In response, GIAT created the G1 with many of the extra features left optional. This allowed them to reduce the price by up to 40%. Specific feature reductions included:
- Omitting the bipod legs
- Omitting the grenade launching sights and barrel fittings
- Omitting the night sights
- Omitting the burst fire mechanism
- Replacing the trigger guard with a molded whole-hand trigger guard
The mechanism stayed the same, and all of the omitted features could be included as options. This still failed to generate any export sales, in part because GIAT came under ownership of FN, and FN’s competing assault rifle options were more profitable than the FAMAS.
The G1 did contribute elements like the whole-hand trigger guard to the mid-1990s G2 model adopted by the French Navy, however.

French Trials FN CAL: Adding Rifle Grenade Capability
Forgotten Weapons
Published 10 Sept 2025In the 1970s when the French Army was looking for a new rifle 5.56mm, they tested a number of foreign rifles alongside development the FAMAS at St Etienne. These included the HK33, the M16, and the FN CAL — and today we are looking at the FN CAL. It already had a four-position selector switch (safe/semi/full/burst), fulfilling one of the French Army requirements. But it did not have sufficient grenade launching capability, and so several examples were modified for trials with unique rifle grenade launching hardware.
Ultimately the HK33 was the best performing rifle, but it was not seen as a politically acceptable option and the FAMAS was chosen instead. I have not seen the trials reports to understand specifically why the FN CAL was unsuccessful, but we know that it was unsuccessful in many other trials, and FN dropped it for the distinct FNC design instead before long.

The Best Operational Briefcase: American 180 & Laser Sight
Forgotten Weapons
Published 5 Sept 2025The “American 180 Security Briefcase” is the best execution of the operational briefcase concept that I have yet seen. The idea is simple; hide a submachine gun inside an ordinary looking briefcase so that it can be carried in the open by VIP security without arousing attention. Sometimes this is done strictly for stowage (see the Uzi coming out of a Secret Service briefcase during the attempted Reagan assassination) and sometimes it is designed to fire from within the case (see the H&K MP5 operational case). This one is meant for firing.
Unlike virtually all other such cases, this one includes a sight, a helium-neon laser. That allows the gun to be actually aimed — what an idea! The firing mechanism is also well thought out, with a manual safety switch that powers the laser and firing solenoid, then a constant-pressure switch for the laser and a pressure pad for the gun. I don’t know who made this, but it was a commercially available product … and a very cool one at that!

Potato Digger at War: Marlin Model 1917 Machine Gun
Forgotten Weapons
Published 27 Aug 2025John Browning’s first machine gun design was a gas operated system that used a swinging lever instead of a linear piston. He presented the first prototype to Colt in 1890, and it went into production in 1895. The US Navy bought a couple hundred, but the Army opted not to adopt it (much to Colt’s surprise). It was offered for sale internationally, but didn’t become very popular until World War One broke out.
By this time, Colt had improved it a bit with a finned detachable barrel, and they started getting orders for thousands of the guns from Belgium, Russia, Canada, Britain, and elsewhere. Unable to keep up with demand, they licensed the design to the Marlin company. Marlin made a few additional improvements (pistol grip attachment, sights, and access door for clearing malfunctions) and made several thousand for allied nations as well as 2,500 fort he US Army to use as training guns in 1917. They further improved the design by changing it to a linear gas piston, and sold some 38,000 to the US military for aircraft use.

Krieghoff’s Bizarre Prototype FG42 Proposal
Forgotten Weapons
Published 23 Jul 2025When the Luftwaffe was looking for its new universal paratrooper rifle, six different German arms companies were asked to submit proposals. Only two actually did; Krieghoff and Rheinmetall. Krieghoff designed this very interesting system, clearly optimized to reduce weight and length as required by the design brief. It uses a tiny vertically traveling locking block and an unusual gas trap system combined with an under-barrel piston. The total number made is unknown, but both fixed- and folding-stock models were produced (the German museum at Koblenz has a fixed-stock example on display). This particular example appears to have been tested after the war by engineers at Springfield Armory by drilling a hole in the gas tube to measure pressure while it cycled.

Roller Delay in France: The H&K 33F (Trials & Export Models)
Forgotten Weapons
Published 14 Jul 2025When France was looking to replace the MAS 49/56 rifle for military service in the 1970s, it tested all of the major rifle options available. These included the Colt M16, FN CAL, and HK33. The HK required some modification to meet French military requirements, specifically the capability to launch rifle grenades. The model 33F was developed specifically to meet these requirements — first as a modified standard HK33, and later as a factory production run. The modifications made include a reinforced magazine well, 4-position fire control gourd (including 3-round burst), a reinforced stock attachment, grenade range rings on the barrel, and a mounting bracket for a rifle grenade sight.
Apparently the HK33F performed very well in trials, but it was ultimately deemed politically unacceptable to adopt a German rifle for the French Army (a policy which has changed now, 50 years later …). Instead, the domestic FAMAS was chosen, along with the SIG-Manurhin 540 purchased in limited numbers for the Foreign Legion.
A second type of 33F came about from the program, however. Berlin police wanted HK33 rifles, but treaty prohibited West German arms from entering Berlin in East Germany. The loophole found was to send the parts to MAS in France, where they were assembled and marked HK33F, thus making them French origin gun which could be sent to Berlin. These rifles had none of the French grenade launching adaptations, and were completely standard HK33s except for the use of heavy barrels. MAS eventually added the G3, HK33, and MP5 to its export catalog in the late 1970s and sold quantities to a number of small countries in the French sphere of influence (including Haiti, Burkina Faso, Lebanon, and others).

URZ: Czech Prototype Universal Modular Weapon
Forgotten Weapons
Published 7 Jul 2025The URZ (Univerzální Ruční Zbraň, or Universal Hand Weapon) was a 1966 project designed by Jiří Čermák (designer of the vz.58 rifle). He envisioned a weapons system family with largely interchangeable elements that could be configured as a service rifle, carbine, light machine gun, vehicular machine gun, or precision rifle. The Czech military was not interested, but Čermák was able to convince the government to allow its development for export instead.
The design is a delayed-blowback system using rollers, and belt-fed. The first few examples were made in 7.62x39mm, but development switched to 7.62x51mm NATO in a rather surprising move. Presumably this was intended for sale to unaligned nations who were interested in the NATO cartridge, but still — seeing its development in then-communist Czechoslovakia is pretty unusual. Ultimately only 9 examples were built before the project was abandoned.

Vickers Heavy Machine Gun
Forgotten Weapons
Published 14 Dec 2016I may be a bit biased here, but I believe that the Vickers gun is one of the best all-around firearms ever made. It was designed during an era of experimentation and craftsmanship, with a quality and care that would make it today prohibitively expensive. It was exemplary in action, and served in every environment on earth through six decades and in the hands of 50 different nations. It was an infantry gun, an aircraft gun, an armored vehicle gun, and a shipboard gun.
Captain Graham Hutchison recorded this account of the Vickers in action during an attack on High Wood in August 1916 (exerpted from “The Grand old Lady of No Man’s Land by Dolf Goldsmith):
“For this attack, [ten] guns were grouped in the Savoy Trench, from which a magnificent view was obtained of the German line at a range of about 2000 yards. These guns were disposed for barrage. On August 23rd and the night of the 23rd/24th the whole Company was, in addition to the two Companies of Infantry lent for the purpose, employed in carrying water and ammunition to this point. Many factors in barrage work which are now common knowledge had not then been learned or considered. It is amusing today to note that in the orders for the 100th Machine Gun Company’s barrage of 10 guns, Captain Hutchison ordered that rapid fire should be maintained continuously for twelve hours, to cover the attack and consolidation. It is to the credit of the gunners and the Vickers gun itself that this was done! During the attack on the 24th, 250 rounds short of one million were fired by ten guns; at least four petrol tins of water besides all the water bottles of the Company and urine tins form the neighborhood were emptied into the guns for cooling purposes; and a continuous party was employed carrying ammunition. Private Robertshaw and Artificer H. Bartlett between them maintained a belt-filling machine in action without stopping for a single moment, for twelve hours. At the end of this time many of the NCOs and gunners were found asleep from exhaustion at their posts. A prize of five francs to the members of each gun team was offered and was secured by the gun team of Sgt. P. Dean, DCM, with a record of just over 120,000 rounds.”
The attack on the 24th of August was a brilliant success, the operation being difficult and all objectives being taken within a short time. Prisoner examined at Divisional and Corps Headquarters reported that the effect of the Machine Gun barrage was annihilating, and the counterattacks which had attempted to retake the ground lost were broken up whilst being concentrated east of the Flers Ridge and of High Wood.
In 1963 in Yorkshire, a class of British Army armorers put one Vickers gun through probably the most strenuous test ever given to an individual gun. The base had a stockpile of approximately 5 million rounds of Mk VII ammunition which was no longer approved for military use. They took a newly rebuilt Vickers gun, and proceeded to fire the entire stock of ammo through it over the course of seven days. They worked in pairs, switching off at 30 minute intervals, with a third man shoveling away spent brass. The gun was fired in 250-round solid bursts, and the worn out barrels were changed every hour and a half. At the end of the five million rounds, the gun was taken back into the shop for inspection. It was found to be within service spec in every dimension.
During its service life, the Vickers was made in .303 British, .30-06, 0.50 Vickers, .50 High Velocity, 7×57 Mauser, 7.65×53, 8mm Mauser, 8mm Lebel, 7.7 Japanese, 6.5×54 Dutch, 7.9x57R Dutch, 7.62 NATO, 7.62x54R, 8x52R Siamese, 11mm Vickers, and three different 40mm cartridges.
The Vickers was retired from British military service in 1968, having finally become obsolete. Its GPMG role was taken over by the FN MAG, and its long range indirect fire role performed by 3″ mortars. The Vickers was a weapon which required training and dedication to master, but rewarded its users with phenomenal endurance and a wide range of capabilities. Among all contenders, only the Browning machine gun can attempt to compare to the outstanding qualities of the Vickers, and even the Browning fails to match the elegance of the stalwart Brit.

Swedish Kulspruta m/36 Double Browning MGs
Forgotten Weapons
Published 18 Jun 2025Despite being a neutral power during World War Two, Sweden had a variety of very interesting small arms — like their dual-mount Browning m/36 machine guns. These were originally adopted because the Swedes wanted a heavier medium MG cartridge and didn’t think their delayed-blowback Schwarzlose guns could handle it. The cartridge was 8x63mm, pushing a 219 grain projectile at 2500 fps. The m/36 Browning was a water cooled gun, an improvement on the older M1917 design. It not only handled the powerful new round, but it could also be easily swapped to the older 6.5x55mm round to use stocks of existing ammunition (and it would be later adapted to 7.62mm NATO as well). Most of the guns were built as matching pairs for antiaircraft use, with mirrors left and right side feeds and in effective recoil-absorbing cradle mounts.

H&K MG4: Germany’s New 5.56mm Squad Machine Gun
Forgotten Weapons
Published 7 Jun 2025Heckler & Koch released the MG4, a new 5.56mm squad machine gun in 2001. It was adopted by the German army in 2005, and then by the Spanish and Portuguese armies in 2007. Alongside its sister weapon the 7.62mm MG5, it is H&K’s current export machine gun.
The MG4 fires from an open bolt, with a 2-lug rotating bolt locking system and a long stroke gas piston operating system. It uses standard M27 NATO links for feeding, and does not have a semiauto selector setting. Mechanically, the MG4 uses a front trunnion into which both the barrel and bolt lock independently — meaning that the quick-change barrel can be removed with the bolt in either the forward or rearward position.
As one would expect for a 5.56mm machine gun weighing 18 pounds, it is very easy to control.

Haenel’s Prototype Simplified Sturmgewehr StG45(H)
Forgotten Weapons
Published 26 May 2025In December 1944, the Haenel company received permission to produce a simplified version of the StG-44 Sturmgewehr. The idea was to keep the mechanical system and controls as similar as possible to the design in use, but simplify the design to reduce the cost and time of production. The design was never completed, and this is the only known surviving prototype. It was most likely captured by American forces when they occupied the Haenel factory in April 1945, although that is not documented. It is a pretty impressive adaptation of the StG design; far simpler to manufacture than the original design. Would it have worked? We don’t know for sure as there are no known German or American test reports, but it certainly seems viable to me.

MG38: Colt’s Interwar Water-Cooled Machine Gun
Forgotten Weapons
Published 7 May 2025After World War One, Colt was the sole owner of license to produce Browning machine guns. With production tooling well established from the war, the company set about looking for international sales. The water cooled .30 caliber (the M1917 in US service, essentially) was designated the Model 1919 Automatic Machine Gun. In 1931, it was renamed the MG38, although basically the same gun as in 1919. It had a few distinctions from the US military pattern, including:
- Manual safety on the backplate
- Self-contained recoil spring
- Large water fill and drain fittings, identical to the ones used on Colt’s .50 caliber guns
- Slightly different top cover latch
Colt offered the guns with lots of options and features, including a variety of calibers (basically any modern rifle cartridge of the time), flash hiders, lightened anti-aircraft bolts, and spade grips (guns sold with spade grips were designated MG38B). From 1919 until commercial production ceased in January 1942, Colt had sold 2,720 water-cooled Brownings in total. Most went to South America in 7.65mm, with Argentina being the single biggest buyer.

Unique British Crankfire .58 Morse Manual Machine Gun
Forgotten Weapons
Published 30 Apr 2025This is a really interesting piece with a mostly unknown origin. It was manufactured in the UK (the barrel was deemed Enfield-made by former Royal Armouries curator Herb Woodend) and is chambered for the .58 Morse centerfire cartridge. The date of production is unknown. It uses a gravity-feed magazine and fires via hand crank. Turning the crank cycles the bolt forward and back, not completely unlike a Maxim gun but without the automatic operation. It came out of a small Canadian museum in the 1950s, but its provenance before that is unknown.

M1922 BAR Cavalry Light Machine Gun
Forgotten Weapons
Published 21 Apr 2025After World War One, there was a lot of tinkering with the BAR by the US military. It was recognized as being a very good platform, but the original M1918 configuration left a lot to be desired. It was deemed too heavy to use effectively from the shoulder, but also not really well suited to sustained fire. In an effort to optimize it for use as a dynamic support weapon by a small squad, the Infantry & Cavalry Board requested a model with a heavier barrel and lightweight bipod in 1920. Six experimental examples were made form existing BARs, and the design was formalized two years later as the Model 1922.
This pattern of BAR has a heavy finned barrel to give it more sustained fire capacity and a folding bipod and rear monopod for more accurate use prone. The Board also experimented with larger magazines, and ended up recommending a 30-round size — although this was never put into production. In total, 500 of the Model 1922 guns were made, all converted from existing BARs. Experimentation continued slowly, and eventually in 1937 a lighter pattern was adopted as the M1918A1. The Model 1922 was formally declared obsolete in April 1941, and virtually all of them were rebuilt to the new M1918A2 pattern for use in World War Two. Surviving examples like this one are extremely rare — this is the only known example in private hands.
