Omlouvám se ale bohužel jsem musel zakázat psaní anonymům, protože nám tu nějaký sabotér vložil "hack" kvůli kterému nešlo přispívat nikomu. Nevím jestli to pomůže, ale snad nad tímto darebákem budeme mít větší kontrolu.
Srdečně zveme do tohoto klubu všechny, kteří se zajímají o zbraně, střelbu a všechno, co s tím souvisí a chtějí si o tom všem v přátelské atmosféře povídat, poradit druhým, nebo se naopak chtěji zeptat na radu.

Kdo chce vystupovat anonymně (tj. bez registrace na Lopuchu), musí si vymyslet nějaké jméno nebo přezdívku a psát ho do každého svého anonymního příspěvku.

Každého přece musíme v diskusi nějak oslovovat, aby bylo jasné, kdo na koho reaguje. Kdybychom měli odpovídat několika bezejmenným anonymům najednou, byla by diskuse značně nepřehledná. Takže, kdo neuvede jméno či přezdívku, ten jako by nebyl.

    AK fm/54: Prototype Swedish Paratrooper Rifle

    As Sweden experimented with updating the AG42 Ljungman in the 1950s, one of the intermediate patterns was the fm/54. This took the 7.62mm NATO short stroke piston conversion already developed and added a 20-round box magazine and a Carl Gustaf m/45 folding stock to it. Not a Carl Gustaf style stock, mind you, but one cut directly off an m/45.

    Animace How a M1895 Lee Navy Rifle Works

    Wikipedia: The M1895 Lee Navy was a straight-pull magazine rifle adopted in limited numbers by the U.S. Navy and Marine Corps in 1895 as a first-line infantry rifle. The Navy's official designation for the Lee Straight-Pull rifle was the "Lee Rifle, Model of 1895, caliber 6-mm" but the weapon is also largely known by other names, such as the "Winchester-Lee rifle", "Lee Model 1895", "6mm Lee Navy", and "Lee Rifle, Model of 1895".

    It fired a 6mm (0.236-in. caliber) cartridge, which used an early smokeless powder, was semi-rimless, and fired a 135-grain (later 112-grain) jacketed bullet. The 6mm U.S.N. or Lee Navy Cartridge was also used in the navy version of the Colt–Browning Model 1895 machinegun.

    URZ: Czech Prototype Universal Modular Weapon


    The 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:

    Why Did This Rifle Have Two Barrels? The Doppelstutzen with Firearms Expert Jonathan Ferguson

    In this week’s episode Jonathan investigates a strange and rare piece from our collection, a flintlock firearm with two barrels, two locks, and a whole lot of unanswered questions.

    From its unique dual-barrel configuration to its connection with elite border troops of the Habsburg monarchy, this weapon tells a fascinating story of experimentation, empire, and engineering.

    Orita 1941: The Original Romanian Submachine Gun

    The Model 1941 Orita was Romania's first domestic submachine gun, but after World War Two the design was upgraded in many ways. The Model 41/48 improved the stock, sights, and controls - and virtually all of the guns underwent these changes. Original configuration 1941 examples are extremely rare today, so I made sure to take this opportunity to show you the one in the Springfield Armory NHS reference collection when I was there filming.

    Thanks to the Springfield Armory National Historic Site for giving me access to this truly unique specimen from their reference collection to film for you! Don't miss the chance to visit the museum there if you have a day free in Springfield, Massachusetts:

    AK4 TP: Estonia's Modernized G3 DMR / Sniper

    When Estonia received a large influx of small arms from Sweden they got both regular AK4 rifles (Sweden's version of the G3) and scoped DMR models. The standard Estonian infantry squad had nine riflemen and one designated marksman, and the scoped G3s became a large part of the DMR armament as the AK4 TP ("Täitsa Pask" - Precision Rifle), replacing the rather disastrous M14TP. Some time between about 2004 and 2010, Estonia updated these rifles with new Magpul stocks and QD Versapod bipods. The scopes were the original Hensoldt 4x scopes used on most G3 variants worldwide. These have since been replaced by new LMT R20L DMRs.

    Thanks to the Supply Battalion of the Estonian Defense Forces Support Command for giving me access to film this rifle!

    Aha, tak mám pravdu jen částečně: se samopalem se počítalo i v některých střílnách LO v členitém terénu, kde by se střílelo na velmi krátké vzdálenost, kde byl náboj 8x57 overkill.

    To s tím opevněním je trochu jinak. Se samopalem se tam počítalo pouze pro ochranné střílny u vchodů, kde jedinou reálnou alternativou bylo používání pistolí. Vchodové střílny byly malé a nemají zevnitř žádnou přípravu na permanentní lafetaci čehokoli. Ve většině případů se za tu střílnu střelec s klasickou dlouhou zbraní ani nevejde. Navíc ta samotná střílna je opravdu nouzová, protože čs. opevnění používalo systém bočních paleb a týlový prostor byl v palebném vějíři minimálně 2, častěji i více, kulometů sousedních objektů.

    U těžkých objektů byl prostor před objektem u vchodu bráněn alespoň jednou standardní střílnou s bajonetovým úchytem pro LK vz. 26 a tam se o nějaké náhradě samopalem pokud vím nikdy neuvažovalo.

    Samopal vz 38: Czechoslovakia's Interwar Drum-Fed SMG in .380

    Military 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 it's 96-round drum magazine (copied format he 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 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:

    Galand de Guerre Model 1872: Too Good for the Military

    Charles 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

    Despite 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.

    Special thanks to Bear Arms in Scottsdale, AZ for providing access to this rare pair of guns for today's video!
