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.

    Now Available: VHS-2 w/ 20-inch Barrel (aka Springfield Hellion)

    Springfield Armory is now importing a version of the the VHS-2 bullpup (commercially named the Hellion here in the US) with a 20-inch barrel. This is the barrel length used in the most common military pattern of the rifle, the VHS-2D. In addition, Springfield's semiauto configuration has the proper military muzzle device, barrel rings for the rifle grenade launcher, and a bayonet lug which fits the standard military bayonet for the VHS-2. This is a pretty cool new option for folks who are interested in the Hellion as a copy of a current-service military rifle.

    The next thing you will need for a proper clone is a VHS magazine well and some of the proprietary VHS-2 magazines...

    Prototype vz.80: Improved Czech vz.50/70


    The vz.50 pistol was a compact .32 ACP (7.65mm Browning) double action pocket pistol used by police forces. It was given a face lift and redesigned the vz.70, and there were plans at one point to further modernize it. The new design would have been the vz.80, but only a few prototypes were made - one of which we are looking at today from the CZ reference library. The would-be vz.80 has a barrel about 1cm shorter than the vz.50/70, and a revised mechanism for removing the slide. And other than a few cosmetic changes to parts like the safety, that's it...

    3D Animation: The Gewehr 43 Semi-Automatic Rifle (WWII)

    The Gewehr 43 or Karabiner 43 was a semi-automatic rifle developed by German gun manufacturer Walther during World War II for the German armed forces. It was chambered in 7.92×57mm Mauser and was the response of the German military to the semi-automatic rifles of the USA (M1 Garand) and the Soviet Union (SVT-40).

    The German invasion of the Soviet Union (Operation "Barbarossa") led to small numbers of the then new Russian semi-automatic rifle SVT-40 (designed by Fedor Tokarev) being captured and returned to Germany for examination.

    The design of the Gewehr 43 was based on that of the earlier G41(W) by Walther, but incorporated an improved short-stroke piston gas system similar to that of the Soviet Tokarev SVT-40. It used a simple gas mechanism powered from a port cut into the barrel about 1/3 of the way back from the end, and replaced the conventional stripper reloads with a more modern 10-round box magazine.

    It was accepted and entered into service as the Gewehr 43 in 1943, renamed Karabiner 43 in April 1944, with production amounting to 402,713 between 1943 and 1945.

    3D Animation: How the Walther P.38 Pistol worked (WWII)

    Walther P.38 was a 9 mm semi-automatic pistol that was developed by German gun manufacturer Walther at the beginning of World War II. By the end of the war, around 1.2 million of the P.38 had been produced.

    The Walther P.38 was intended to replace the costly Luger P08 (the first pistol chambered in 9mm), although many Luger P08, Walther PP and Walther PPK (later made famous by James Bond) pistols remained in service among officers within the German Army during World War II.

    Since the German army wanted to prevent that weapons captured by the Allies could be connected to an arms factory in Germany (to prevent them from being bombed), the pistols were given a code instead of a manufacturer name. That's why the codes "ac" (Walther Zella-Mehlis), "cyq" (Spreewerk Grottau) or "byf"/"svw" (Mauser Oberndorf) are engraved on the pistols, that were produced during WWII.

    After World War II the pistol was again manufactured and again adopted by the then newly founded German Bundeswehr under the name Walther P1 from 1957 until 2004. The successor to the P1 in the Bundeswehr is the Heckler & Koch P8.

    The Walther P.38 had a major influence on the development of the Beretta 92 by Italian gun manufacturer Beretta, which was adopted by the US Army under the name M9 as the successor of the Colt M1911 (used by the American troops in World War I, World War II, the Vietnam War and others) as official sidearm in 1985.

    The P.38 features a open slide design (like the Beretta 92/M9) and was the first locked-breech pistol to use a double-action/single-action (DA/SA) trigger (the earlier double-action PPK was an unlocked blowback design, but the more powerful 9×19mm Parabellum round used in the P.38 mandated a locked breech design).

    Double-action/single-action means, that pulling the trigger cocks the hammer before firing the first shot with double-action operation. The firing mechanism extracts and ejects the first spent round, cocks the hammer, and chambers a fresh round for single-action operation with each subsequent shot.

    The moving-barrel mechanism is actuated by a wedge-shaped falling locking block underneath the breech. When the pistol is fired, the barrel and slide recoil together, until the locking block drives down, disengaging the slide and arresting further rearward movement of the barrel.

    The slide continues its rearward movement on the frame, ejecting the spent case and cocking the hammer before reaching the end of travel. Two recoil springs on either side of the frame and below the slide, having been compressed by the slide's rearward movement, drive the slide forward, stripping a new round from the magazine, driving it into the breech and re-engaging the barrel; ending its return travel with a fresh round chambered, hammer cocked and ready to repeat the process.

    3D Animation: How a GSh-18 Pistol works

    The GSh-18 is a striker-fired semi-automatic pistol developed by the KBP Instrument Design Bureau in Tula during the 1990s and chambered in 9mm (9x19mm Parabellum).
    The pistol's name is derived from its designers Gryazev and Shipunov and its double stack magazine with a capacity of 18 rounds. The GSh-18 is a rotating-barrel, short recoil, locked-breech pistol with 10 locking lugs spaced equally around the barrel.
    The GSh-18 may be employed using standard 9x19mm Parabellum rounds, but was designed for the high velocity 7N31 9x19mm round.

    Token of Appreciation: a Presentation Sokac SMG

    The Šokac was one of the more prolific Croatian domestic submachine guns of the Homeland War. This particular example is one that was specifically presented to the police chief of the town of Slavonsky Brod (the town where the guns were made). It is a mid-range production example, with the polymer lower house (instead of metal), and 25-round magazines. It was fitted in a briefcase - not one of leather, but one one M81 woodland camouflage - the pattern copied and used by Croatian forces. In addition to the gun and magazines, the case also includes cleaning supplies and a large baffle-type silencer.

    Thanks to the Sisak Municipal Museum for giving me access to film this!

    Mosin 91/30 PU: Soviet Standard WW2 Sniper's Rifle

    The Mosin M91/30 PU is the most recognized Soviet sniper rifle of World War Two, but it was not their first. It was preceded by the Model 1931 PE, the Model 1936 PEM, and also the scoped version of the SVT-40 semiautomatic rifle. The SVT was intended to become a universal infantry rifle as well as a sniper's rifle, and the short 3.5x PU scope was designed specifically for it (earlier PE and PEM scopes we long, and interfered with the ejection port of the SVT). Mosin sniper production was shut down in the summer of 1940 as the SVT started to be manufactured.

    However, field use showed that the SVT was inadequate as a sniper rifle. It had problems with first shots going to a different point of aim than subsequent ones, a barrel that heated rapidly and would string out shots, and generally insufficient accuracy overall. In August 1942 it was declared ineffective - something new was needed to replace it. The solution was to design a mount to fit that new short PU scope (which was fast and cheap to make) to the standby M91/30 Mosin Nagant, and put that into production as quickly as possible. An Izhevsk engineer named Kochetov designed a good mounting system, which was adopted in August 1942 just as the SVT was being retired. Both Tula and Izhevsk began new production of M91/30 PU snipers, with the first rifles ready in October and December of 1942 respectively.

    By the end of 1944 close to 400,000 of the Mosin PU snipers had been built, enough to fully equip the Red Army. Production was shut down, but the rifle remained the Soviet standard sniper rifle until replaced by the SVD Dragunov in the 1960s. The example we are looking at today was made at Ishevsk in 1943 and given to Poland as military assistance after the war, where it was refurbished and put into storage.

    The Manda: Croatia's Minimalist .50 BMG

    The Manda is a rifle that was designed for the Croatian Special Police at the beginning of the Homeland War in 1991. At that point, the Special Police (basically the SWAT teams) were basically the only really well-trained fighters in the country with combat experience. They wanted .50 BMG anti-material rifles for the war that was breaking out, and the Croatian Ministry of the Interior developed and produced the Manda for them.

    Specifically, the rifle was designed by engineer Petar Vucetic (and named after his sister). Mechanically, it is a very simple rifle, with two large locking lugs, a tubular stock, M70 AK pistol grip, and a barrel made form a turned-down Browning M2 bolt with a large muzzle brake. A total of 84 were made, fitted with Leupold scopes and mounts with integrated BDC cams for use from 300 out to 1000 meters.

    A big thanks to the Croatian Police Museum (Muzej Policije) in Zagreb for giving me access to film this cool piece for you! Check them out at: https://muzej-policije.gov.hr

    ta montáž je na tom asi nejpodezřelější. Klidně by mohl být puškohled i opravdu historickej ale naprasenej na tu pušku později. Ale jak jsem psal - já se zajímám v historii o Evropu (hlavně o Prusko), takže neumím posoudit.

    (paradoxně novodobé zbraně mám vše made in USA a Evropské zbrojovky mne moc neuchvátily)

    Díkvšem!

    Ty staré dlouhé optiky se objevují v různých westernech; možná nejikoničtější je Josey Wales, když přestřelí lano toho přívozu. Van Cleefa jsem s ničím podobným nenašel, ale má tam těch záznamů nějak podezřele málo. A byly různě dlouhé, ano :)

    _

    Nicméně mně nešlo o délku, ale (a) o tu prapodivnou montáž, (b) o ten divný zaměřovač uvnitř, (c) o to tvrzení, že je to bez skla (ale to taky prostě může být neznalost/lež, kdo ví).

    Každopádně jsem takovouto montáž nikdy a nikde neviděl. Už dávno před občanskou válkou se dělaly montáže s „mikrometrickými“ šrouby, koncepčně hodně podobné moderním puškohledům, akorát že neposunovaly vnitřní skrytou rouru, ale byly usazené zvenčí a posunovaly to celé:

    _

    A aby v tom nebylo žádné sklo mi taky nedává smysl, stejně jako kolegovi 666. Jakou by to pak mělo výhodu proti otevřeným mířidlům s dioptrem? Podle mne naprosto žádnou, naopak, bylo by to po všech stránkách horší.

    Osobně z toho mám taky pocit, že to je samo domo novodobé ACW-like, ale křivdit tomu nechci.

    Ty dlouhé puškohledy používaly během ACW obě strany (Konfederace známá svojí Whitworth), ale na mimoevropské válčení moc odborník nejsem a ten ocs konkrétní kus neznám.

    Jinak to běžně přibližovalo - byl to smysl toho puškohledu. Moc nevidím důvod mít tu trubku na pušce bez optiky.

    Aha, okay, tak asi ano. Nicméně toto co má Clint je trochu jiný model zaměřovače. Mám ale dojem, že Van Cleef měl tu trubku opravdu až na konec hlavně jako je tady na obrázku.
