Forgotten Weapons
Published 16 Jul 2025The CZ247 was developed for Czechoslovakia’s post-war submachine gun trials, where it was pitted against the ZB47. It was a simple blowback 9x19mm SMG with a number of interesting elements, most notably the ability to fire with the magazine either vertical or horizontal. In theory, this made the gun more compact for use in a jungle sort of environment (vertical) or to allow a shooter to get much lower to the ground when shooting prone (horizontal). In practice, it really isn’t very important, and requires a bit of extra complexity in the gun’s design. The CZ247 also has a neat safety mechanism for preventing unintended firing and a stripper clip guide built into the stock (both of which would be incorporated in the vz.48 SMG that was eventually adopted).
When the CZ247 failed to win the military trials, CZ got government permission to sell it on the export market. A contract for 10,000 guns was quickly obtained from Egypt, but before the guns could be shipped the export permission was cancelled by the government. Czechoslovakia opted to support Israel in its declaration of independence in 1948, and the government decided to not send weapons to Egypt which might be used against Israel. This left the guns sitting in CZ warehouses, and the basically all stayed there for a few decades. Eventually most were sold to Nigeria in 1967 and Ethiopian in 1977 — and as a result they show up occasionally in African and Middle Eastern conflict zones to this day.
Thanks to CZ for giving me the opportunity to take this example out to film and also to shoot for you!

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).
Many thanks to the IRCGN (Institut de Recherche Criminelle de la Gendarmerie Nationale) for allowing me access to film these rather rare HK variants for you!

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.
Thanks to the Czech Military History Institute (VHU) for graciously giving me access to this one-of-a-kind prototype to film for you! If you have the opportunity, don’t miss seeing their museums in Prague:

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.

3D printing and firearms
On the social media site formerly known as Twitter, ESR discusses a recent user notification from one of the 3D printer companies to their users:
I’m told that 3D printed gun parts are far more sophisticated than this Liberator from 2013, but I’m sure nobody would actually do that, right? It would draw the attention of various government agencies for sure.
The recent flap about FlashForge attempting to forbid its customers from printing gun parts means it’s time for another reminder about technological risk.
Their weasel-worded climb-down carefully avoids stating that they never collect data on what you print. They only say they don’t collect data during your prints. The wording is so careful that I think we can conclude they do in fact ship telemetry on your print jobs when g-code arrives at the printer, immediately before printing.
So I repeat a warning I’ve given previously: never buy a 3D printer that requires an internet connection to function. And, always assume that if the printer’s firmware isn’t open-source, it is written to spy on you and could at any time prevent you from printing disapproved objects.
Oh, and never trust FlashForge again or buy their products, no matter how much groveling they do. After this, it’s safest to assume that anything they say about respecting the privacy and autonomy of their customers will be a lie. Hear that, @ff3dprinters
?We need to make a public example of FlashForge. Other vendors need to hear that shit like this will not be tolerated, that attempting to constrain what their customers print will do them permanent and irreversible damage.
It’s possible that this was merely a blunder on FlashForge’s court, and the attempts they’ve made so far to recover are compounding blunders, but they have sincerely repented of trying to control their customers. That’s too bad; in order to create the right incentives bearing on the future behavior of other vendors, we must show no mercy. We must make them hurt – ideally, to the point of being driven out of business.
And really these warnings apply to all “smart” devices, not just 3D printers. Unless you can audit the source code, the only safe assumption to make is that the firmware is spyware, controlware, and malware.
Device vendors need to know that we do not forgive, and will not forget.

Marlin 1897 Bicycle Rifle
Forgotten Weapons
Published 23 Feb 2016Marlin’s 1892 lever action rifle in .22 rimfire caliber proved to be a very popular firearm, and so the company released an improved version in 1897, offered only as a rimfire takedown model. The 1897 would also prove very popular, and the same basic design would continue later as the Model 39.
One interesting variant of the 1897 offered was a Bicycle Rifle. While the rifle was generally available only with fairly long barrels, the bicycle version had a 16″ barrel and full-length magazine tube. This was sized specifically to fit in a special case (disassembled) underneath the top bar of a bicycle frame, allowing kids to easily use their bicycles to take these rifles to their favorite shooting spots.
While the 1897 itself was popular, the bicycle variant was not, with Marlin sales records showing only 197 sold.

Volksturm VG-5, aka VK-98
Forgotten Weapons
Published 15 Sept 2015By the beginning of 1945, the Nazi government in Germany was looking to find cheaper ways to equip the Volksturm, and solicited bids and designs from several major arms manufacturers. The Steyr company created a crude but effective version of the Mauser 98 which was dubbed the VK-98 or VG-5. Mechanically it is identical to a K98k, but has much less attention paid to aesthetic finish and many simplified parts.
In total, 10,000 of these Steyr rifles were made. Despite commonly held notions of them having totally random parts, there are actually a relatively small number of discreet variations in the production sequence and the rifles have definitely class characteristics — which I will examine in the video.

Samopal vz 38: Czechoslovakia’s Interwar Drum-Fed SMG in .380
Forgotten Weapons
Published 25 Jun 2025Military interest in a submachine gun was late in Czechoslovakia, but by the late 1930s a development program was put into place. Interestingly, the main use case for an SMG was seen as being a replacement for a rifle-caliber LMG in fortification mounts. The thought process seems to have been that a large volume of fire was the necessary element to keep invaders away from border fortresses, and the ballistic power of the fire was not so important.
The vz38 was designed by František Myška, chambered for the 9x17mm (.380) cartridge used by the vz22/24 pistol then in service. It was tested against the ZB26 light machine gun. It proved reliable and effective, and its 96-round drum magazine (copied from the Finnish Suomi) was a particularly nice element. An initial order was placed and the gun was formally adopted into service, but production never began. Instead, German occupation of the country put an end to the project and only 20 preproduction examples were ever made.
Many thanks to the VHU — the Czech Military History Institute — for giving me access to this very rare example to film for you. The Army Museum Žižkov is a part of the Institute, and they have a three-story museum full of cool exhibits open to the public in Prague.

Galand de Guerre Model 1872: Too Good for the Military
Forgotten Weapons
Published 23 Jun 2025Charles François Galand is best known for his simultaneous-extraction Model 1868, but he also developed a very good solid-frame revolver. This was specifically for the French 1871 military trials, which specifically required a solid frame. The Galand was chambered for 12mm Galand (with its distinctive very thick rim), held 6 rounds, operated in either single or double action, required no tools to disassemble, and had very simple but durable lockwork. The gun was very good, and was a very tight competitor for the other trials finalist, the Chamelot-Delvigne. Ultimately, it lost out because it was the more expensive of the two options.
For more information on the Model 1873 Chamelot-Delvigne that won the French trials, I suggest the C&Rsenal video on that model:

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.

AR-1 “Parasniper” – The First Armalite
Forgotten Weapons
Published 11 Jun 2025The first rifle produced by Armalite began in 1952 as a project between the brothers-in-law, Charles Dorchester and George Sullivan (no relation to later Armalite engineer L. James Sullivan). Sullivan is the chief patent attorney for the Lockheed Aircraft Company, and the two have the idea to produce an ultra-light rifle using aircraft industry materials like fiberglass and aluminum. They create a company called SF Projects and get to work using Remington actions. They fit aluminum (and then later aluminum/steel composite) barrels and foam-filled stocks and the result is a rifle that weighs less than 6 pounds with a 4x scope fitted. The first ones are chambered in .257 Roberts, but this shortly gives way to the new .308 Winchester cartridge.
Sullivan and Dorchester make a connection with Richard Boutelle, who is very much a “gun guy” himself and also head of the Fairchild aircraft company. The idea of the rifle appeals to Boutelle, and Fairchild was looking to diversify its operations – and so Fairchild agrees to buy SF Projects, renaming it the Armalite Division of Fairchild.
The idea of the rifle was for civilian hunters who want a gun that is light to carry for long distances and also military specialists like airborne troops who need lightweight gear. The Army tests the AR-1 in 1955 and finds some fairly serious problems with it. There are reliability issues, and also accuracy shortfalls. When the composite barrel heats up, differential stresses cause the point of impact to shift. This foreshadows the catastrophic failure of a composite barrel in AR-10 testing, but that is a story for another video. Ultimately after two rounds of testing the Army rejects the rifle, and that is pretty much the end of it. Armalite moves its focus to other projects, namely combining aircraft industry materials with the self-loading rifle of their other designer, Eugene Stoner. That, of course, will become the AR-10.
Since I know folks will ask, the AR projects between 1 and 10 were thus:
AR3: Stoner-type rifle in hunting configuration
AR5: Air Force survival rifle
AR9: Shotgun
The designations 2, 4, 6, 7, and 8 were set aside to drawing board projects that never materialized.

A Modern Stocked Pistol: B&T’s Universal Service Weapon (USW)
Forgotten Weapons
Published 9 Jun 2025The genesis of the B&T USW was a two and a half hour car ride home from a youth hockey game, when Karl Brugger and a friend were thinking about how to improve police effectiveness with handguns. What would make a handgun more accurate in practice? Clearly a red for and a shoulder stock. So how does one add those elements to a pistol while maintaining easy carry in a service holster? The answer was the USW.
The first prototypes were built on AT-84 Sphinx pistols (a Swiss-made copy of the CZ75). The first production run used Sphinx components, but with newly made frames and slide that incorporated cocking surfaces forward on the slide and an extension off the frame to mount the side-folding stock and Aimpoint Nano optic. Only a few of these were made, as the project was never all that popular.
Other experiments included conversions for other pistol models, with the SIG P320 being the most practical. Clamp-on conversion kits were made for guns like the CZ P10, Walther PPQ, and Glock.
Perhaps the most influential outcome of the project was the optic. Aimpoint originally developed the Nano as B&T’s request, but in the original form is was not nearly as reliable as Aimpoint desired. It was iterated and ruggedized (and renamed to avoid a lawsuit over the Beretta Nano pistol) and became the very successful Aimpoint Acro.

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.

Gerät Potsdam: Mauser Copies the Sten Gun
Forgotten Weapons
Published 2 Jun 2025In the fall of 1944, the Mauser company was given a contract to develop drawings of a direct copy of the British Sten gun (code named Gerät Potsdam), and to manufacture 10,000 of them. In fact, they were to make two different sets of drawings; one suitable for large factory use (like their own) and one for use with distributed small shops making parts for final assembly elsewhere (which is how much of British Sten production was done). The contract was fulfilled and 9972 guns in total were produced and accepted by the German military in November and December of 1944.
Why would Germany was a copy of the Sten? Well, they actually had a decent number of them. The Allies were air-dropping Stens all over Europe, and a lot of those drops were captured by German troops, not the resistance fighters they were intended for. By the end of the war the Germans were in desperate need of arms, and the Sten was both simple and already in some German use with the Volkssturm … so it actually was not a totally unreasonable idea to produce more of them.
Today, the Potsdam is an extremely rare gun to find. The two visible identifying features are the magazine well and barrel shroud, which are both made with a folded and spot welded seam. The barrels are also identifiable as they have 6 groove rifling, which the British did not use in the Sten.
Before the Potsdam production was finished, Mauser began working on further plans to simplify the design. That would be the Gerät Neumunster, aka the MP 3008. For that part of the story, see my video on the MP 3008:

DSA’s Unique Titanium FAL Project
Forgotten Weapons
Published 28 May 2025DS Arms got some billet titanium and decided to make a batch of titanium receivers and other parts. This turned out to be a nightmarish amount of work, and two of the receivers had to be scrapped, leaving only 10 completed. They also made a number of other titanium parts, including flash hiders (which this rifle has) and gas blocks (which this one does not). Between the titanium and aluminum parts and the choice of a lightweight configuration, this FAL tips the scale at just UNDER 7.5 pounds (3.4kg). That is a very remarkable achievement, and does so without making sacrifices in durability or features. It is slightly sharper recoiling than a standard 50.00 FAL (which weighs almost 10 pounds / 4.5kg), but not uncomfortable at all — the recoil is less than I had expected.
Unfortunately DSA does not appear to have any plans to make addition titanium receivers, but this small batch serves as a very cool proof of concept!
