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.

	Stocked Pistols: Great or Garbage? Stocked pistols: they have been around as long as pistols have been around, but are they really all that useful?

	Al Kadesih: Iraq's Exceptionally Rare Dragunov Copy The Al Kadesih (also sometimes spelled Al Kadesiah or Al Qadisiyah) is an Iraqi copy of the SVD Dragunov DMR/sniper rifle. It is not an exact copy, though, as it uses an AK-style stamped receiver and trunnions in combination with the fire control system and short-stroke gas piston of the SVD. The rifles were made at the eponymous Al-Quadisiyah Establishment in Iraq, a small arms factory set up with Yugoslav assistance to make small arms. That factory produced a copy of the Yugoslav M70 called the Tabuk as well as other weapons. Rather than completely reverse-engineer the SVD, they adopted the M70/AKM design to do the job. Production appears to have run from 1988 until 1991, with another batch made in 2003 before the US invasion. The total number made is unknown, but certainly only a few thousand. The rifles appear to have been as much for presentations and gifts (gold plated ones, specifically) as for combat use, and they are very rare to see in combat photos.

	SIG M18: New USMC Service Pistol (and Little Brother of the M17) The SIG 320 was adopted by the US Army as its new M17 full-size service pistol, but that was only have of the Modular Handgun System. The other half was the M18, a compact version of the same pistol, with a 3.9" barrel (compared to the 4.7" barrel of the M17). The Army did also adopt the M18 for MP and CID personnel, but the other service branches chose to go with the M18 as their standard sidearms. Notably, this includes the Marines, who will be using the M18 to replace the M9, M9A1, M007 (Glock 19M) and M45A1 (1911). Being a highly modular design, the M18 uses the same basic fire control module as the M17, as well as the same magazines. The slide and grip module are shorter to match the shorter barrel, and multiple different sizes of grip module are available to reasonably fit anyone between the 5th and 95th percentile of hand size. While the initial batch of M17s were made with tan controls and subsequently returned and sold on the civilian market, no M18s appear to have been returned from service. However, SIG continues to run the military M18 production line making "contract overrun" pistols exactly to military specification, and that is what we are looking at in today's video. These have TC serial number prefixes, along with other military features: Single-screw optics plates Braided recoil springs Tool-based takedown Military slide markings

	Otterup Model 69: From German Sword to Danish Plowshare The Schultz & Larsen company in Otterup, Denmark was a venture formed by a gunsmithing shop and a very successful target shooter to make precision rifles. In 1919, they are able to purchase a bunch of German arsenal tooling for pennies because of the Treaty of Versailles. They made a number of rifles, both military and sporting, in the 1920s and 1930s. In the aftermath of World War Two, they turned to using surplus German K98k rifles as the basis for hunting and precision sporting rifles. They make a series of different models (1952, 1958, and ultimately 1969) with various improved features. The model 1969 is the final version, which uses a German bolt and receiver fitted with a heavy new barrel (typically in 6.5x55mm), a new stock with a significant pistol grip (similar to the Swedish CG63), a very nice Danish target trigger, and a set of precision aperture sights. The rifles were a staple of Danish competition shooters for several decades.

	Animace12.5 inch RML Technical Details Some notes on the technical features of the 12.5 in 38 ton Rifled Muzzle Loaded gun from 1885, covering the mechanism in the gun carriage and fitted to the platform. The method of building the gun from wrought iron rod and constructing it using concentric coils to pre-stress the inner parts are illustrated in concept - there is no guarantee that the actual machinery used at the time bear any resemblance to that shown in the movie - concepts only. Gun design is covered briefly, concentrating on showing how internal pressure was measured using crusher gauges fitted to test guns. Finally, a method of measuring muzzle velocity is shown, and a hint given for the mathematics needed to calculate velocities at different ranges, which in turn resulted in range tables used for actual firings. When watching this animation, bear in mind the technology available at the time. No computers , no electronics, rudimentary electrics (wet cell batteries). So measuring time (for muzzle velocity) used the known constant - gravity. Electric motors would be subject to speed variations depending on the state of the batteries. However, the level of mechanical skills were impressive. Machinery capable of finishing to an accuracy of a few thousandths of an inch on rotating masses weighing several tons were available, as were the artisans. Even more impressive was the level of mathematical skills needed to calculate the stresses that would be experienced in a gun, to determine the thickness of the coils, and the actual dimensions to be machined so that outer coils would shrink onto inner coils and so pre-stress them, while at the same time expanding sufficiently so that heated outer coil could be slipped over an inner component. Range tables were calculated laboriously by hand or with primitive calculating machines. The other thing to note is that these guns were still using Gunpowder - an explosive. The Mark 1 gun used pebble powder - gunpowder compressed into small cubes in an attempt to slow down the explosion and so reduce the rate of gas generation. The Mark II gun would use Prismatic gunpowder, where the explosive was formed into larger prisms, slowing down the rate of burning still further but also requiring a longer barrel to ensure all the powder was burnt before the shell left the barrel.

	Slovenian Modularity: Perun X16 "PDW" in .300 Blackout I was first introduced to the Tinck Arms Perun X16 at Lynx Brutality 2022 in Slovenia, and it is an interesting system emphasizing modularity and simple disassembly. I opted to use one (a 5.56mm carbine) at Lynx Brutality 2023 this year, and it ran perfectly for me. So I figured we should take a look at the version that is available in the US. The US distributor is AEA Arms. and they offer both complete guns and also upper assemblies. For the complete guns, they adapt Kaiser USA polymer lowers (which is pretty easy). What I have today to look at is a "PDW" variant - a 7.5" barrel in .300 Blackout, with a Riflespeed adjustable gas block. Predictably, it also ran without any problems...

	The Rarest Chassepot: Rifle for the African Cavalry The rarest pattern of factory-made Chassepot is the fusil modèle 1866 pour la cavalerie d'afrique - the Model 1866 rifle for African cavalry. Just 12,000 of these were made by St Etienne in the spring of 1869, as a way to equip the mounted French troops in Algeria with the new needlefire rifle that the rest of the Army had. After some field testing with standard Mle 1866 Chassepot rifles, it was determined that really all they needed was a change in sling position, so that riders could carry the weapon slung diagonally across the back. To do this, a number of changes were made to the rifle. The stock was strengthened, reinforced at the trigger guard, the rear sling swivel moved to the trigger guard, and a wider third barrel band added with the front sling swivel. After the Mle 1866 cavalry carbine went into production in 1870, the need for these specialized rifles disappeared. No more were made, and as they were worn out they were rebuilt into standard configuration Mle 1866 infantry rifles. Very, very few survive today, and I'm and very excited to have this one to show you!

	New Springfield Echelon: Croatia's Chassis System Pistol The Springfield Echelon pistol was released today, and it's a significant step forward for Croatian manufacturer HS Produkt. In an effort to appeal to new military and police tenders as well as introduce a forward-looking new design, the company has brought out a pistol based on a serialized chassis like that of the SIG P365 and P320. HS Produkt recognized that their previous design (the XD and XD-M in the US and the HS2000 and HS9 in Europe) was falling behind. Its grip safety was getting it rejected from a lot of major tenders, but rather than just made a new versions without that element, they chose to move to a whole new platform. Work began about 2 years ago, and it is now ready for market. For now, the Echelon is available only in this basic configuration, although that does include a lot of premium features - light rail, ambi controls, tritium front sight, and an optics mounting plate. A threaded barrel is also available separately. In the future, I have no doubt we will see a wide variety of other configurations from subcompact to oversize competition models - that is one of the core strengths of the chassis system, after all.

	Crogar M91: MP40 Meets Yugo M56 in the Croatian Homeland War SKM was a small industrial manufacturing company in Croatia that began making submachine guns in 1991 to equip Croatian fighters in the Homeland War. Their product was the M91 Crogar, which is a selective-fire, open bolt SMG chambered for 7.62mm Tokarev. It uses the magazine from the Yugoslav M56 SMG, along with its rotating bolt handle feature as a safety mechanism. The bolt and recoil spring are based on the MP40, and a folding stock inspired by the side-folding AKs made in Poland, Romania, and Hungary. Total production quantity is not known, but was not more than a few hundred at most. The build quality on these guns was quite good, and they were reportedly well liked by those who got them. A big thanks to the Croatian Police Museum (Muzej Policije) in Zagreb for giving me access to film this rare piece for you! Check them out at: https://muzej-policije.gov.hr

	Italian GWOT Steel: the Beretta AR-70/90 While the Italian military did adopt the AR-70, it did not actually issue them to all troops. Most continued to use the 7.62mm BM-59 until 1990 when the Beretta AR-70/90 was adopted. This rifle was a substantial rework and improvement of the AR-70, using AR-pattern magazines and a 1:7" twist barrel to run the SS109 62gr ammunition chosen as the new NATO standard in 1981. The 70/90 also added a 2-position gas regulator to the design, while carrying over the folding bipod and grenade launching capabilities of its predecessor. The AR-70/90 was made in semiautomatic from by Beretta for the civilian market, but only after US regulation prohibited its importation. As a result, these rifles were essentially nonexistent in the US until a few years ago, when a number of cut-up parts kits were imported. Several small shops set up to make them into semiautomatic rifles with new US-made receivers, including Brimstone Arms, who made this one for me.

	Bernardelli P018S: A Hipster's Service Pistol Bernardelli is (was) an Italian firearms manufacturer in the Val Tromp dating back to the 1600s...but whom few people have ever heard of. They produced 1889 Bodeo revolvers between the World Wars, and after World War Two they had a line of pocket pistols that were never particular popular or respectable in the US. In 1982, the company released the P018, its effort to create a military and police service pistol. On paper, it was basically completely average for the time. It used a Browning tilting-barrel system, DA/SA firing mechanism, right-handed manual safety and magazine release, steel frame, and double-stack 15-round magazines. It was quite well made, and worked very well. It just never managed to be at the right place and the right time, and was never adopted by any organizations of significance. A series of pistols followed the original P018, including the P018 Compact, P018S (this example; with a decoder and simple plastic grips), P.ONE regular, P.ONE Compact, and VB Practical (and IPSC competition model). Early models were offered in 7.65mm Parabellum (for maximum hipster points), 9mm Parabellum (for normal people), and 9x21mm (for the Italian civilian market). With the P.ONE, .40 S&W was also added to the offerings. None were bad guns, but none were commercial successful and only a few thousand of all types were made before production ceased in the 1990s.

	Experimental Romanian Paratrooper PKM Romania adopted the PKM in 1966, and began manufacturing their own direct copy at Cugir. In the 1990s, the plant designed a model intended for paratroopers, with a shortened barrel and unique side folding stock. Romanian special operations and paratroop units tested them, but declined to purchase any - funding was tight and the breakup of the eastern bloc meant offensive troops like paratroopers were less of priority. A total of only 400 of these guns were made, and all of them sold to export clients. This one is also fitted with a picatinny optics mount a tai-rail handguard made specifically for it by B&T. Thanks to DSA for giving me access to film this one in their reference collection!
