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.

    Chrysanthemums in the Snow: Finnish Arisaka Rifles

    When Finland took its independence, the most common type of firearms in the country was the Mosin Nagant - and the second most common was the Arisaka. An assortment of Type 30, Type 35, and Type 38 Arisaka rifles and carbines were left to the Finns by former Russian occupying soldiers. Where did they come from? Well, a few were captured by Russian during the Russo-Japanese War. But most of them were rifles purchased by the British from Japan early in World War One to free up scarce SMLE rifles for front line infantry. Once British production caught up with demand, the now-unnecessary Arisakas were sent to Russia as war aid.

    The Russians tended to give Arisakas to second-line troops like the British had, using standard Mosin Nagants for the fighting infantry wherever possible. One of the duties that required armed troops but didn't involve much actual shooting was maintaining the Russian military presence in Finland to guard against possible German attack (Finland being a Russian province at that time). When the newly independent Finland disarmed Russian garrisons, many of the rifles they got were Arisakas.

    The Finnish military standardized on the Mosin fairly quickly, but the Finnish Civil Guard used Arisakas into the mid 1920s. Not all of the Arisakas originally captured were actually turned over to the Civil Guard; many were kept by individuals. Those that did enter Civil Guard inventory will typically have Civil Guard district numbers (with "S" prefixes) on the stock or barrel. The Guard did perforce regular maintenance of Arisakas, and a batch of 500 new barrels was purchased from SIG in the 1920s to replace worn-out barrels - these are marked with SIG's name on the side of the chamber, and are very scarce to find today.

    The only typical mechanical modification found on Finnish Arisakas are Russian in origin - changes to prevent the magazine release from being accidentally pushed by a heavy glove. Some examples have the magazine release button ground down, and some have a small sheet metal clamp fitted to prevent accidental pressing of the release. These rifles will also have a Tokyo Arsenal insignia overstepped on the chrysanthemum, done when the rifles were originally sold to the British.

    AR57: Fun Times with a Tiny Carbine (aka FSS Hurricane)


    The AR-57 is a system developed by Rhineland Arms in the early 2000s which uses the FN P90 magazine (and its 5.7x28mm cartridge) in an AR upper. The magazine mounts on top of the barrel, and it ejects downward through what would normally be the AR magazine well. Any standard AR lower can be used, although the company (AR57; a separate firm spun off for this product) sold complete guns using OEM receivers form Aero Precision.

    The uppers were made in three barrel lengths, and I have here an example of a first generation full-length rifle and a second generation SBR with a 6.25" barrel and a GSL Technology suppressor nested inside the handguard.

    Further thanks to Battlestar Gatlactica for the loan of the 1st generation rifle!

    Sven: Na pouzdra se používají hlavně různé polyamidy (též pod názvem nylon a někdy různé značky jednotlivých výrobců). Většinou nějak zpevněné, třeba nasekaným skelným vláknem nebo skleněnými kuličkami. Třeba Glock používá Zytel od Dupontu: https://www.mobility-materials.com/knowledge/zytel-plus-performance.html

    P. S. zprávu jsem viděl, snad se ozvu během víkendu.

    Yugoslav M72: The Early Balkan RPK
    When the Yugoslav Peoples' Army began AK development, they produced the M64 infantry rifle and the M65 support weapon. The M65 had a longer and heavier profile barrel and a bipod - and in its very early experimental iterations a quick-change barrel mechanism and a folding carry handle. By the time it entered regular service it was the M72, the carry handle was gone, and the barrel was fixed in place.

    The internal parts of the M72 were interchangeable with the standard M70 rifles, and they could also use the same magazines - although a drum was made specifically for the M72 to allow more sustained fire. Note that like the M70, the M72 originally had an automatic hold-open for empty magazines, but this was removed to allow compatibility with standard AK pattern magazines. The original M72 used a distinctively shaped milled receiver like the very first M70 rifles. Two later versions would follow; the M72B (slab-side milled receiver and pinned barrel) and M72B1 (stamped receiver).

    Thanks to Polenar Tactical for arranging access for me to film this excellent example of an early M72!

    Dotazjak se prosím jmenuje ten plast, ze kterého se dnes dělají pouzdra závěru moderních zbraní? Kdesi jsem na to narazil a teď to zaboha nemůžu najít.

    Why did these percussion pistols have such straight grips? With firearms expert Jonathan Ferguson

    This week's obscure firearm stems from the French city of Marseille in the mid-19th century. Made by the Viallon family, these weapons catch the eye as a result of their modern looking grip. Jonathan Ferguson explains why they look so different compared to other percussion pistols at the time.

    Sven na gúglí trubku nepolezu, abych to ověřil, ale tipuji, že plnohodnotné odkazy budou jen tam. Toto že je copypaste, v němž jsou jejich konce uříznuty a nahrazeny trojtečkami, a tedy zjevně nefunkční.

    HS2000: The Perfected Croatian Pistol that Became the Springfield XD



    With the HS95, Croatian manufacturer IM Metal (later to become HS Produkt) had learned how to effectively manufacture a good pistol. However, the design had some shortcomings and had not been accepted by Croatian police forces, nor had any commercial export contracts materialized. The company recognized that the way of the future was polymer framed, striker-fired pistols - so they set out to create just that.

    Working with a variety of military and technical experts, they developed the processes to manufacture a polymer frame of the requisite strength and durability for a handgun. Mated with a simple-but-effective slide assembly, the HS2000 was born. The development began in 1998, the first pistols were made in 1999, and mass production was underway by 2000. The guns were adopted by Croatian Army and police forces, and Intrac of Tennessee contracted to import 10,000 of them into he US in 2000. The following year, a sales rep from HS Produkt and a company rep from Springfield Armory had a chance encounter at a rather boring conference, and began talking. The result was an import deal for a pistol to be sold in the US as the eXtreme Duty - which has led to more than 6 million pistols sold today.

    The first incarnation of the HS2000 actually didn't meet US import requirements; a "target thumb rest" and loaded chamber indicator were added to the design for the initial Intrac imports. A trigger safety was added at the same time, and the design underwent a series of small improvements and iterations over the first year or two of production. We will take a look at all these variations today.
