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.

    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!

    The best helical magazine ever? With firearms and weaponry expert, Jonathan Ferguson

    The relatively rare Danuvia VD-01 is the focus for this week's What is this Weapon? episode. While boasting a relatively unremarkable spot in the story of firearms development, the VD-01 does have some interesting features, including polygonal rifling and a helical barrel.

    There's no such thing as an AK-47? With firearms and weapon expert Jonathan Ferguson

    The 'AK-47' is the ubiquitous label for the most recognisable group of firearms on the planet, but would you be correct in calling all AK-type rifles AK-47s? Is there indeed any such thing as an 'AK-47'?

    Join Jonathan Ferguson as he examines the lineage of the most produced firearm family of all time to see what, if indeed anything can truly call itself an AK-47.

    Remington M1903A4 Sniper at the Range

    Today we are taking the Remington M1903A4 out to the range for some shooting. This was the standard US sniper rifle during World War Two, and I'm curious to see how one actually handles...

    Improving Mosins: The Estonian M1935



    When Estonia declared independence from Russia in 1918, it had no formal military. After winning a 2-year War of Independence, the nation needed to set up its own armed forces. The rifles available in Estonia were a mix of Mosin Nagants, Arisakas, Pattern 1914 Enfields, and German Mausers. The most common were the Mosins, and Mosins would form the bulk of Estonian arms until World War Two.

    The initial Estonian military work was to refurbish, repair, and clean the Mosins it had, which resulted in about 40,000 good-quality rifles, plus another 64,000 purchased from the UK in 1922. Extensive military training took its toll though, and by the late 1920s many rifles were once again in poor shape. At the point, a project was established to make some improvements while still retaining the basic M91 Mosin form. This escalated to a major modification and rebuild program in the early 1930s.

    The first model to be made was a marksman's rifle, which a shorter and heavier barrel, better sights and a better trigger. Lessons from this work led to the development of the Model 1935 military short rifle, which is what we have today. Between 1935 and 1940 a total of 6,790 of these rifles were produced. Like the Finns, the Estonians only manufactured a few parts for the guns, taking receivers, bolts, magazines, and other small parts from their inventory of spares leftover from scrapped rifles in the early 1920s.

    Unfortunately, the M1935 rifles never had a chance to see significant use, as Estonia had no real choice but to submit to Russian occupation in 1940.

    Thanks to Texas Guns and Ammo for the loan of this rifle to film, and to my Estonian friend Aku for research assistance!

    Rearming West Germany: The G1 FAL


    Today we are taking a look at a German G1 pattern FAL. The initial purchased of the G1 were actual made by the German Border Guard (the Bundesgrenschutz). In the aftermath of World War Two, the western Allies decided to perpetually disarm Germany, and German security was provided by French, British, and American forces. As the Iron Curtain fell across Europe, that attitude softened - West Germany was on the front lines of the Cold War, and could be a valuable ally against Communism in the East. Thus in 1951, the West German Bundesgrenzschutz (Border Guards) were formed and armed - basically with all WW2 Wehrmacht equipment. Looking to improve its small arms in 1955/56, the BGS tested a number of modern rifles and decided to adopt the FAL.

    The BGS initially ordered 2,000 FAL rifles from FN, with wooden hand guards and a fixed flash hider (essentially a standard Belgian FAL) - these are known as the "A" pattern. A second BGS order for 4,800 more rifles followed, this time of the "B" pattern with a metal handguard and folding bipod. This was the first use of an integral bipod on the FAL, and would go on to be a popular option for other buyers.

    In 1955, the German Army is reinstated as the Bundeswehr. Looking over the BGS rifle testing, the Bundeswehr also decides to adopt the FAL, and places and order for 100,000 rifles - the "C" pattern. These include sights lowered 3mm by specific German request, as well as a set of swappable muzzle devices (flash hider and blank-firing adapter).

    Ultimately, FN was unwilling to license FAL production to West Germany, and this drove the Germans to adopt the Spanish CETME as the G3 rifle, which it was able to license. The Bundeswehr G1 rifles were eventually transferred to the BGS and later sold to other allies as surplus.

    Special thanks to Bear Arms in Scottsdale, AZ for providing access to this rifle for video!

    Fascinating Finds in a Guadalcanal Relic Museum

    Today I'm visiting the Solomon Islands War Memorial Museum in Honiara (the capital city on Guadalcanal). This is a private museum run by two brothers on the island, and it is filled to the brim with artifacts recovered from the jungles and battlefields, both American and Japanese. From Coke bottles to 20mm cannons, everything conceivable off a battlefield is represented here, including some really interesting items you might not expect. A few things that stuck out to me include:

    - WW1 V-B type rifle grenades used by the US Marines
    - Dutch small arms, including KNIL Madsen LMGs used by the Japanese
    - Field-modified M1918 American trench knives

    Ultima Ratio: RAID and the Founding of PGM Precision


    Thanks to Creedmoor Sports for sponsoring this video, and providing a couple of fine shooting mats to experiment with. Check them out for all your long range competition needs!

    The Ultima Ratio was the rifle that created PGM Precision as a company. It originated with a tender for a new sniper rifle by RAID (Recherche, Assistance, Intervention, Dissuasion), a French Police intervention unit formed in 1985. They initially used Steyr SSG-69 rifles, but wanted something better. Six companies entered rifles for consideration in 1989/1990, and the two finalists were Accuracy International and a guy from Savoy named Gilles Payen.

    Payen's rifle won the trials thanks to its accuracy, its resilience against heat issues (thanks to the massive finned barrel) and Payen being French. He was allegedly more responsive to RAID requests for changes, and let's be honest - the elite French police are going to prefer a French-designed and French-made rifle if they can get one that meets the requirements.

    Payen was a good designer and shooter, but he did not have any real production capacity, so he partnered with brothers Roland and Alain Gonnet and François Morier to form the company PGM Precision. They delivered the 20 rifles for RAID in 1991, and displayed the rifle at that year's MILIPOL exposition. It proved popular, and the company has expanded from there.

    Rifling on the *outside* of the barrel? The SR-11 with firearms and weapons expert Jonathan Ferguson

    An Antipodean entry with some extremely extremely rare features, but like so many weapons of this series, this week's entry was destined to be a footnote in the annals of firearms history.

    Created by Australian, Russell Robinson, inventor of other extremely odd looking firearms, the SR-11 had an auto-ejecting magazine and reverse rifle grooves on the outside of its barrel in an attempt to counterract effect of the spin of the bullet to improve accuracy. Join Jonathan as he calls in his science pals to see if all that effort was really worth it.

    M1903A4: America's WW2 Sniper Rifle


    The United States Army entered World War Two with neither sniper rifles nor a sniper training program. As troops began to see combat, requests began to come back to the War Department that both were urgently needed. The newly-adopted dM1 Garand rifle was going to be a bit tricky to mount optics on, so while that program began a contract was made with Remington to product a scoped version of the M1903A3 Springfield rifles. This was designated the M1903A4, and it would serve as the US Army's standard (and essentially only) sniper rifle during the war.

    The 03A4 used a Weaver 330C commercial scope (given the military designation M73B1) on Redfield Junior mounts. The scope offered just 2.5x magnification, and used a simple crosshair reticle. It was reasonably effective, but not hardened for military service. The rifles did not have any other particular special work done to them, like bedding or improved triggers. A total of 28,365 were delivered, all made by Remington. They are found in the following serial number ranges:

    3,407,088 - 3,427,087
    4,000,001 - 4,015,000 (only about 3,000 in this block were used. Some duplicated 03A3 numbers; these were given an addition "Z" prefix)
    4,992,001 - 5,784,000 (only about 6,300 were used of this block)

    Chatellerault Experimental SMGs: MAC48 & 48LS

    Continuing our look at the French submachine gun designs from the Chatellerault Arsenal, today we have the MAC48 and MAC48LS (lightened and simplified). In the development program that would eventually lead to adoption of the MAT-49, Chatellerault began with a couple of very light delayed blowback designs in 1947 ( • MAC Model 1947 Pr... ). When those were rejected, they turned to a style of gun more influenced by the Sten and M3 Grease Gun in 1948.

    The regular MAC48 used a wooden fixed stock and pistol grip, and was chambered for 9x19mm, using MP40 magazines (France did not have its own standard 9mm SMG magazine at this point, and MP40 magazines were plentiful). The bolt is clearly derived from a Sten, and the gun is heavier than the 1947 models but also much less complex.

    A second pattern was the MAC48LS, a lighter and even simpler version of the design. This used a removable cover at the rear of the receiver for disassembly, and replaced the wooden stock with a telescoping wire stock like the American M3. It also brought back the folding magazine well, which the MAC48 did not have. This pattern is starting to get fairly close to the final design that was adopted (although it would be a Tulle design, not a Chatellerault one).

    There were a few other variations on the MAC48 pattern, including a long barreled one with a bipod, and a version with twin triggers to allow semiauto fire - unfortunately we don't have access to either of those today.

    Many thanks to the French IRCGN (Criminal Research Institute of the National Gendarmerie) for generously giving me access to film these unique specimens for you!

    Samopal, který v případě zaseknutí bylo doporučeno umýt v louži (PPS-43)

    Design samopalu, který dodnes překvapuje svou jednoduchostí a vyrobitelností, se zrodil ještě díky jednomu člověku.
    Při vytváření svého prvního vzorku použil Alexej Ivanovič Sudajev originální konstrukční řešení nalezená poručíkem techniky dělostřelecké akademie Ivanem Konstantinovičem Bezručko-Vysockij, který vyvinul vlastní verzi samopalu.
    Koncem dubna 1942 Sudajev představil svůj vlastní model zbraně pro polní zkoušky.
    Navenek měl jeho samopal mnoho společného s prototypem Bezruchko-Vysockij, což není překvapivé, protože v něm Sudaev použil schéma fungování pohyblivých částí a reflektoru použité nábojnice vyvinuté Bezruchko-Vysockij, takže její práce spolehlivější.

    Last Gasp of the German Maxim: the Air-Cooled MG 08/18

    The MG 08/18 was developed at the very end of World War One as a lighter alternative to the MG 08/15. It used an air-cooled barrel, and between not needing water and having lighter parts it managed to be about 6 pounds less weight than the 08/15. Only a few hundred appear to have been produced before the end of the war, and they were not used by the German military during the Weimar era (the Mg 08/15 was). The 08/18 barrel jacket served as the basis for the MG34 barrel shroud, interestingly.

    Thanks to Limex for giving me access to this very rare gun to film for you!
