Forgotten Weapons
Published 1 Dec 2025The FG-42 caught the attention of a lot of countries at the end of World War Two. The British and Swiss both used it as the starting point for some developments. The US went one step simpler, and simply cut up a captured FG-42 to make into the T44, the first prototype of what would become the M60 machine gun.
This project was done in 1946 by the Bridge Tool & Die Company, who spent about six months reinforcing an FG42 and adding an MG42 feed system to it to create an unholy hybrid kludge of a gun. It was, however, successful enough to justify continuing the project. Only this one example was made before moving on to much more practical models built from the ground up instead of hacking up captured German guns.

T20 Family: Springfield Makes the Garand a Grenade Launching Sniper Machine Gun
Forgotten Weapons
Published 17 Nov 2025Late in 1944 the Ordnance Committee recommended adoption of a magazine-fed, select-fire version of the M1 Garand as a new standard US infantry rifle. Both Springfield and Remington developed rifles to meet the requirement, with Springfield’s being the T20 and Remington’s the T22.
The Springfield design went through several iterations from the original T20 to the T20E1 and T20E2, with the capability to launch rifle grenades, mount optical sights, and fire in either semiautomatic or full auto. The first examples of the final T20E2 design were ready in June 1945, but the program lost momentum in August when Japan surrendered. It did continue slowly until 1949, providing some of the basis for the eventual M14 rifle.

Taking advantage of the temporarily insane market price for tungsten
Tim Worstall has a business idea to capitalize on a current price fluctuation in the tungsten market … and you wouldn’t need to build a massive mine or a large smelter for the purpose:
“Making friends with the 50-cal” by 416thTEC is marked with Public Domain Mark 1.0 
.
There are times when the prices of weird metals just get wholly out of hand. Like, absurdly, nonsensically, out of hand. This is of great comfort to the usual morons as they can then point out that markets are not rational. They’re morons because no one has ever used — other than morons — “rational markets” to mean always correct markets.
The actual defence of markets is that they produce less absurd prices less often than allowing morons to determine them.
But, OK, odd prices.
Those of a certain age might recall back around the millennium tantalum prices went ballistic. They had been $200 a kg and they went to $2,000 a kg. This was because a little bit of Ta is essential to make the capacitors that make a mobile phone work. Mobile phones were proving to be pretty hot shit and so demand rose, demand rose faster than new mines could be opened and so the price went ballistic.
[…]
So, tungsten. A fair old use (and while everyone’s screaming about this and China it’s a minority use, by a long way. The major use is actually in the teeth of digging machines as tungsten carbide. If you’ve a scrap yard of those drop me a line!) is in armour piercing bullets and shells. Which, when in use are dispersed on the battlefield and no, it’s not worth going out and collecting those. The brass shell casings, especially of artillery, those are but let the specialists do that — too many dud rounds that can still go bang for amateurs to do that.
Tungsten prices are weird. The price is quoted at metric tonne unit in WO3 concentrate. Which is, now, perhaps $2,400 (which is insane, but there we are). An mtu, well, WTF? To get to the tungsten price divide by 8 (OK, OK, 7.92). So, $300 kg tungsten metal. The scrap price will be less than that, obviously and etc.
And, well, something that some do do. Firing ranges.
Lead has a value, most bullets are made of lead, a lot of bullets are fired at the range. There’s a big bank of earth behind the targets at the range to ensure we don’t hurt no kangaroo etc with bullets flying over the horizon. It does actually pay, every so often, to go dig out that bank of earth for the bullets embedded in it. Lead scrap has a price.
Can you see where this is going? Find the ranges they test their armour-piercing ordinance on and offer to dig out their bank behind the targets. Collect the tungsten scrap — and the lead, but separate them — and make bank on the vast, stupid, insane price of tungsten. Shovel, wheelbarrow, sieve, sweat, this works.
If we can find the shooting ranges they try their tungsten bullets out upon. Each bullet is going to be in the 3 to 7 grammes range, that sort of thing. So we’ll need 200 bullets to get a kg at $300 (less scrap discount!) which sounds like a lot. But if we find the ranges where they teach firing the .50 cal armour piercing machine gun rounds then … well, if they’ve not dug through that bank for a few years $$!!

The Original AR-15: Serial Number 6 in Original Configuration
Forgotten Weapons
Published 1 Nov 2025The very first AR15 rifles submitted to US government trials were extremely lightweight, with an assortment of interesting features that did not last long. They had top-mounted charging handles, one-piece hand guards, very thin barrels with plain muzzles, and a different safety selector configuration than became normal later one. Updates and modifications were made to virtually all of the original rifles, but today we have a chance to look at serial number 6 in the Springfield Armory collection — which is still in completely original configuration.

M1918A2 MOR: How to Make a Non-NFA BAR
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.
