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.

    Custom DeLisle: A .45ACP Mini-Mauser in Classic Sporting Lines

    Today we are checking out a bespoke gunsmith's project; a DeLisle-inspired .45ACP Mauser built by Lars Rannstad Slang of Oslo. Using a commercial small-ring Mauser action, he fabricated a new bolt head, trigger guard, follower, and large aluminum mono-core suppressor to built a rifle that functions like a classic SOE DeLisle silenced carbine but with the aesthetics of a classy 1920s sporting rifle. It feeds from 5-round stripper clips, with an internal magazine instead of the original detachable magazine configuration of the DeLisle.

    Thanks to Lars for giving me a chance to do some shooting with this awesome unique piece! You can follow all his projects on Instagram:

    Cugir Model 92 "Dragana" Mauser: Hunting Rifles From MG34s

    With the fall of communism in Romania, the Cugir Arsenal complex lost its government financial support. Looking for commercial products to sell to keeps its workers employed, the factory turned to producing hunting rifles for the domestic Romanian market. This was possible because the factory had a stock of spare parts for maintaining the older weapons of the Romanian Patriotic Guards (equivalent to a territorial home guard). These included vz.24 Mausers and MG34 machine guns.

    The Model 92 was a rifle built on a vz.24 Mauser action. The first 500 or so were chambered for 7.92x57mm Mauser, using turned-down spare MG34 barrels. When these barrels were exhausted, Mauser barrels were used instead and chambered for .30-06. A few thousand in total were made between 1992 and 1996, and remained available for sale into the late 2000s. The fancier versions have features like double set triggers and Cugir-made telescopic sights. This particular example was given as a gift to the Romanian Prime Minister in 2006.

    Thanks to MP Armory and A.N.C.A., the Romanian national firearms collectors' association, for making this video possible!

    FN M249S Semiauto for Military Collectors

    In 2015, FN USA introduced a Military Collector product line - semiautomatic versions of their military contract small arms. These were the M4, M16, and - most interestingly - the M249 SAW. The SAW is a version of FN's Minimi light machine gun, developed in 1974 and adopted by the US in 1982. The semiauto version, designated M249S, is exactly the same as the military M249 but adapted to fire from a closed bolt in semiautomatic only, making it a non-NFA item like any other semiautomatic rifle. The semiauto conversion as done by essentially chopping off the back of the bolt carrier to act as a linear hammer, thus allowing the use of the original style of trigger mechanism. Since its introduction in 2016, FN USA has made more than 10,000 of these rifles, truly proving the depth of American collector interest in this sort of thing (much to the surprise of the Belgian FN administration...).

    Wieger 942: East Germany Makes a 5.56mm AK

    East Germany purchased a license for production of the AK-74 in 1981, but that license was for domestic use only. There was an apparent market for export production AKs in the western 5.56mm cartridge, and so the East Germans developed their own new rifle to fill that demand and bring in some much-desired hard currency. That new project would be designated the 940 series of rifles, with fixed-stock 941, folding stock 942 (the subject of this video), compact carbine 943, squad automatic 944, and designated marksman's 945. Development began in 1985 and the first prototypes were ready in 1988. The plan was to make 100,000 rifles the first year and 200,000 per year thereafter, but the fall of the Berlin Wall ended those (very optimistic) plans.

    In total, it appears that about 10,000 of the Wieger (named after the town of Weiss, where they were manufactured) rifles were made. These consisted of about 7500 model 941 rifles for India and about 2000 folding-stocked 942 rifles for Peru. The last ones were sold in 1992, and they are quite scarce to find today.

    Interestingly, there is a batch of clones in the United States. The InterOrdnance company produced reproduction Wieger furniture, and installed it on a version of the Cugir SAR-3 5.56mm AK rifles made specifically for this purpose. Those are a bit scarce, but can still be found in the US.

    Mendoza 1934: Mexico's Domestic LMG

    Rafael Mendoza was Mexico’s premier domestic arms designer, and the Model 1934 LMG is probably his most successful design. He began work on it in 1929, and it entered testing with the Mexican Army in 1932. It was formally accepted by the Mexican Army in 1934 (hence the designation) and would serve into the mid 1950s. Mendoza was a private civilian, but production of the gun took place in the state-owned National Arms Factory in Mexico City, with Mendoza himself receiving no royalty or licensing fees. Instead, his company was given a contract to make the magazines for the guns.

    Mechanically speaking, the Mendoza 1934 is a gas-operated, rotating bolt, magazine-fed LMG chambered for 7mm Mauser (the standard Mexican military cartridge at that time). Production actually began in 1939, and would continue into the 1950s with about 5,000 made in total. The main purchaser was the Mexican military, but some were also exported to Guatemala, Costa Rica, and Cuba (both Batista and Castro). With he end of World War Two, there was a huge glut of American surplus arms, and Mexico adopted the BAR and the Browning 1919, which replaced the Mendoza in Mexican front line service.

    If you are interested in more details about the Mendoza 1934 or any of Rafael Mendoza’s other designs, I highly recommend Luis Eduardo Gonzales’ book on Mendoza, available in English in both print and Kindle versions:

    Tour of Sport Systems Dittrich: Reproduction WWII German Rifles

    I recently had a chance to visit Sport Systeme Dittrich, a firm in Germany that manufactures high quality reproductions of German World War Two small arms. They were the manufacturers of the PTR-44 Sturmgewehr copies about 10 years ago, and they are now working with a US partner (DK Production Group) to import their guns into the US. The first one to be ready here was the BD-38 (copy of the MP38), and the StG-44 will be the next one coming...

    How a Stechkin Automatic Pistol Works

    Wikipedia: The Stechkin or APS (Avtomaticheskiy Pistolet Stechkina = Автоматический Пистолет Стечкина) is a Soviet selective fire machine pistol chambered in 9×18mm Makarov and 9×19mm Parabellum introduced into service in 1951 for use with artillery and mortar crews, tank crews and aircraft personnel, where a cumbersome assault rifle was deemed unnecessary. Seeing service in a number of wars such as the Vietnam War, Russo-Ukrainian War and Syrian Civil War. The APS was praised for its innovative concept and good controllability for its size. However, the high cost of the weapon, complex and time-consuming machining, combined with a limited effective range, large size and weight for a pistol, and fragile buttstock have been mentioned as a reason to phase it out of active service in favour of assault rifles such as the AKS-74U. The pistol bears the name of its developer, Igor Stechkin.

    Pistols Fit For a King: Early Percussion Revolvers with Curatorial Assistant Christian Wellard

    Most modern revolvers can trace their lineage all the way back to Colt's designs of the 1840's, but not these...

    In this episode of Up In Arms, Curatorial Assistant Christian Wellard is looking at a beautiful set of early percussion revolvers belonging to King Ferdinand II of Sicily.

    Romanian Model 1879 Martini-Henry Rifles & Carbines

    Following its experience in the Russo-Turkish War, the Romanian Army was quite impressed by the Martini-Henry rifle in Turkish service. Unlike so many Western observers who were taken by the Winchester repeating rifles that actually didn't make much battlefield impact, the Romanians recognized the all-around quality of the Martini. So after the war when looking to equip their own newly independent army, they went to Britain for Martinis. They were not able to get rifles made in Britain, but did purchase a license to make the rifle in .45 Gatling, which they took to a factory in Witten, in the German state of Wurtemburg. This factory was newly opened, run in part by Friedrich von Martini himself - so what better place to get Martini rifles?

    An initial contract for 60,000 rifles and 8,000 carbines was accepted by the factory and delivered fairly quickly. When the Romanians came back for more guns the factory had gone bankrupt, however. Subsequent orders were instead made form OEWG Steyr in Austria. In total, Romania acquired about 145,000 Martini long rifles and between 12,000 and 18,000 carbines. They were replaced by the Model 1893 Mannlicher in the 1890s, and thus were never used as a front-line rifle in any major combat. They served in World War One in a secondary role only.

    Thanks to the King Ferdinand I Military Museum for giving me access to these examples and to A.N.C.A. for coordinating the visit! If you are in Bucharest, make sure to stop in and visit the museum:

    Landstad 1900: A True Semiautomatic Revolver
    Headstamp Publishing - the best publisher of exhaustively researched and beautifully photographed firearms reference books.

    The Landstad Model 1900 is a magazine-fed, semiautomatic revolver designed by Norwegian Halvard Folkestad Landstad, who lived in Kristiana (now called Oslo). He designed the gun on his own dime, and presented it to military trials in 1901, which it failed miserably. The gun has a six-round detachable box magazine of 7.5mm Nagant cartridges, a two-chamber cylinder, and a simple blowback action. Its firing cycle is to chamber a round from the magazine into the bottom cylinder chamber by manually cycling the action. The trigger is a long double-action type which rotates the cylinder 180 degrees so the cartridge is in line with the barrel and releases the striker to fire the round. Upon firing, the bolt cycles open, extracting and ejecting the empty case, rechecking the striker, and chambering a new round from the magazine into the bottom of the cylinder.

    The purpose of this overly complex system was to provide a semiauto action which did not ever leave a live cartridge under the striker, in the name of safety. Only one example was made, and its bolt broke after just 5 or 6 rounds fired. It was repaired almost immediately, but the Norwegian military had was not interested in further development, and nothing more came of the program. A few years later in 1908 Norway would institute a more serious semiauto pistol trials program which led to adoption of the Kongsberg 1914 (a slightly modified Colt 1911).

    Thanks to Jan for allowing me to disassemble and film this one-of-a-kind piece for you!
