Praga I: A Blow-Forward Bullpup Semi-Auto-Selectable Vickers Gun (Ad-free)
Added 2025-01-15 12:00:02 +0000 UTCThe Praga I was the first machine gun design from noted Czech arms designed Vaclav Holek. Three examples were made for Czech military testing in 1922, but they were not acceptable. Instead, this design served as the first stepping stone to the eventual development of the ZB-26, perhaps the best of the interwar light machine guns.
Mechanically, the Praga I is largely based on the Vickers/Maxim system except with a locking wedge instead of a toggle joint. It also uses a forward-moving gas trap sort of action instead of recoil operation like the Maxim/Vickers. The fire control mechanism is essentially a Vickers lock, just built into the receiver of the gun instead of in a moving bolt or lock. It is a truly fascinating system!
Many thanks to the VHU - the Czech Military History Institute - for giving me access to this fantastic prototype to film for you. The Army Museum Žižkov is a part of the Institute, and they have a 3-story museum full of cool exhibits open to the public in Prague.If you have a chance to visit, it's definitely worth the time! You can find all of their details (including their aviation and armor museums) here:

Very impressive lock work in the back room

2025-06-04 12:26:08 +0000 UTCI got a chuckle when the third hand appeared in the video. I'm so accustomed to you disassembling guns solo, that it was a great "Wait... What?" moment.

2025-01-16 21:44:44 +0000 UTCFun to watch and learn about, but if there were ~any~ casings that manage to slip the feed, that gun would be out of commission for a week it feels like.

2025-01-16 14:59:32 +0000 UTCDoes the trigger and firing mechanism have more parts than the rest of the machine gun combined? That's a whole lot of bits squeezed into that "backroom".

2025-01-16 00:20:21 +0000 UTCGreat "old school" mechanisms, intricate steel parts. And those "doors", one with the feed block... Full production would need a big factory full of milling and shaping machines.

2025-01-15 16:37:08 +0000 UTCReally interested in what the recoil impulse must feel like.

2025-01-15 14:27:22 +0000 UTCthat shroud certainly looks very very cool. dito its shortness. I don't think so short did the design any good but looks badass. DANG that is EASY to maintain! lift the housing and access to everything? how nice is that! last thing that would be needed is a cutaway for training. nicely explained (like a tom and jerry mousetrap blueprint).
