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.

    Successor to the Scout: Q's 8.6mm Fix

    There is a ton to go over in this video...I noticed the Fix when it first came out, but it didn't become really interesting to me until the version in 8.6mm Blackout hit the market. Fundamentally, the Fix is a very light, modular, and ergonomic bolt action utility rifle. In 8.6mm, I think it is a magnificent hunting weapon - virtually silent while offering excellent terminal performance with a heavy expanding projectile.

    I am going to be using this rifle with an AGM Rattler TS35-640 thermal optic in Midnight Brutality, so stick around for that video tomorrow!

    Nylon 66: Remington's Revolutionary Plastic Rifle


    In the 1950s, Remington decided that it needed an inexpensive new .22 self-loading rifle to add to its catalog. In looking at how to reduce the cost of such a rifle, they hit upon the idea of using polymer to replace the wooden furniture typically used - and to replace the metal receiver as well. Remington was owned by DuPont at the time, and DuPont had developed an excellent strong polymer which they called "Nylon" - specifically, Nylon composition number 66.

    Remington engineers developed a massively complex and expensive mold to inexpensively stamp out monolithic polymer .22 rifles in the mid 1950s. They knew this design would cause concern to a large part of their market because of its non-traditional construction, and so they put the new rifles through hundreds of thousands of rounds of grueling testing. It passed these trials with flying colors, and was released in January 1959 to pretty rave reviews. By the time it was finally taken out of production in 1987, more than 1,050,000 of them had been produced - a fantastic success on a pretty big gamble.

    Thanks to Dutch Hillenburg for loan of this example to show you!

    Animace12.5 inch Rifled Muzzle Loading Gun, 1885

    The 12.5 inch Muzzle Loading Gun Mark I of 1885 fired a shell weighing 820 pounds (372 kg) to a range of 6,000 yards (5,586 M). It weighed 38 tons (38,610 Kg) and was generally used as a coastal defence cannon mounted in forts. The gun could fire 3 types of shell - a Palliser armour piercing shell against armoured warships, a common explosive shell for unarmored ships and a shrapnel shell to be used against small craft and assault forces.

    The animation is based upon installation of 7 12.5 inch RML guns at Fort Nothe, Weymouth (UK), which protected Portland harbour. The fort, built between 1860 and 1872, was upgraded to mount these large guns in 1893-4. The underground magazines and shell rooms were also enlarged.

    The video shows how the very large guns were loaded, aimed and fired from within the cramped casements of the fort, and without the use of power or hydraulics. The loading drills are taken from the Handbook of the RML 12.5 inch 38-ton Gun, dated 1885, with much assistance and advice from historians familiar with the period.

    Fort Nothe is open to the public and has many interesting exhibits covering gunnery and torpedoes from the 1880’s to the 20th century.

    While this video focuses on the drill and fort, a further video is planned to show the construction of the gun and the mechanisms of the platform. Please watch this space.

    Chinese Warlord C96 Carbine from Taku Naval Dockyard

    Today we are looking at a second Chinese Warlord-Era C96 Mauser carbine. These were made as fancy sporting or presentation arms for important people - just as the original Mauser-made C96 carbines were. This example was made at the Taku Naval Dockyard, a facility initially set up to maintain the Beiyang Fleet but which expanded into arms production. Based on the pair of Nationalist flags on the buttplate, this was most likely made in the late 1920s.

    "Le Formidable" Pre-WW1 Pocket Revolver at the BUG Match


    "The Formidable" was the name given to one of many different civilian pocket-carry revolvers made by the French Manufrance firm in St Etienne. This particular model was introduced in 1895, although it went through a significant redesign in 1902. The example I have here is the later pattern, which was sold until 1916 (when arms production completely shifted to military weapons). It is a 5-shot, swing-out cylinder double action revolver chambered for the 8mm French Ordnance (aka 8mm Lebel Revolver) cartridge. The double action trigger pull is very heavy at about 17 pounds, and the hammer is bobbed to prevent snagging in a pocket.

    Hunting Rifles for Greenland: M1917 Enfield


    Greenland is a remote and desolate land without a significant industrial base, but there is a demand for hunting rifles there. As the place has long been a Danish colony since 1814, its trade was restricted to Denmark - including rifles. The Danish military received a substantial number of M1917 Enfield rifles in .30-06 caliber, and they were used by the Danish Home Guard after World War Two until being eventually sold as surplus. Some of those surplus rifles were modified by the Greenland Trade conglomerate ("Kalaallit Niuerfiat") and sold as commercial hunting rifles.

    The conversion pattern used was to mill off the rear aperture sight and replace it with a fixed open notch dovetailed into the chamber area of the barrel. A new front sight was installed to match the height of the rear notch, and the bayonet lug was ground off for some reason. This particular example was originally manufactured in 1917 and used by the Canadian military before being sent to Denmark and eventually sold as surplus.

    The M1917 was the standard rifle for the Sirius Patrol, a Greenland military force established during World War Two to prevent establishment of German outposts on Greenland (and very effective in this work). The force still exists today, and still uses M1917 rifles, now paired with 10mm Glock 20 pistols. The commercial sporterized M1917s like the one in this video are not made from Sirius Patrol rifles, however.

    Thanks to the Southern Iceland Shooting Association for helping me film this and other cool guns in Iceland!

    Strangest Firearm Actions Ever Designed
    In this video, we look a five of the weirdest firearm actions ever designed, from crank operated breech-loaders to guns with puck-shaped magazines. We also discuss how successful they were and why most of them failed to make an impact.

    Project Best Millimeter: SIG/GrayGuns vs Hi-Point 10mm


    When I heard about Hi-Point releasing a 10mm pistol (the JXP 10), I knew I needed to do something fun with it. Hi-Point is often derided - and often for good reasons - but fundamentally the Hi-Point design does exactly what it is advertised to. It is a functional and extremely inexpensive pistol. The company has been making essentially the same gun for 25+ years, and they have build a very efficient manufacturing process that allows them to offer a gun that is safe and pretty reliable for a ridiculously low price point. Of course, it does sacrifice a lot of niceties in the process, but that is the tradeoff for the cost.

    Anyway, the question for today is:

    Who would win in a fight, one GrayGuns custom SIG P220 Elite or six Hi-Point JXP-10s? Let's find out!

    Test 1: Accuracy
    Test 2: Reload speed
    Test 3: Mud
    Test 4: SPINNER SUDDEN DEATH!

    Disclosure:
    Bruce Gray of GrayGuns provided the P220 Elite on loan; it has been returned to him. Hi-Point donated the six JXP 10s because let's be honest, they can't really be resold after that mud bath and the cost of shipping them back is more than their MSRP anyway. We have some ideas for fun future use of them...

    Ohio Ordnance HCAR: The BAR of the Future


    The Ohio Ordnance HCAR (Heavy Counter Assault Rifle - a rather fanciful name) is what happens when you take the US military development track of the Browning Automatic Rifle, and bring up to the present day. Why would someone choose this particular product to modernize? Well, because eOhio Ordnance was already making standard semiautomatic reproduction of the M1918A2 (World War Two era) BAR, and this type of modernization was a fairly obvious extension of that project.

    The HCAR retains the .30-06 chambering of the BAR, but gives it much-improved controls. The magazine release is now a handy AK-like lever, the safety sits nicely under the thumb of a right-handed user, and a proper pistol grip replaces the traditional wrist of the M1918A2 (a change that Colt and FN made in the 1930s, but which never got into the US Ordnance system). The rifle fires from a closed bolt, and Ohio Ordnance added a bolt release control as well - something not needed on the open-bolt originals. Picantinny rails on the receiver and handguard allow for mounting of optics, bipods, and other accessories.

    A few holdovers from the US military ancestry inclose the A2-style magazine guides, and the rather tricky disassembly procedure (which was also much improved by FN in the 1930s, but not adopted by the US). The barrel is offered in either 16" or 20"; both dimpled for weight reduction. The receiver, bolt carrier, and many other parts have been substantially lightened, bringing the HCAR in at 11.75-12.5 pounds depending on barrel length - a huge reduction from the 19 pounds of a standard M1918A2.

    The question is, what is the purpose of the HCAR? It is a very expensive rifle, and one is tempted to try to see it in a modern tactical light because of its styling. However, there really isn't much a .30-06 can do that can't be accomplished by any number of lighter and cheaper rifles with more widespread aftermarket support. To me, the purpose of the HCAR is simply to have fun with. It is a very cool rifle, and does not need to be justified as aTier One Operator's choice. It is reliable, pleasant to shoot, accurate, and makes form a fun head-turning day at the range. Sometimes that's all a gun needs to be...

    Gnome et Rhône R5: A Foiled Communist Arms Plan



    The R-5 was a French-made copy of the Sten produced after the 1944 liberation of France. It was built by Gnome et Rhône, a French company best known for making aircraft engines. The Sten was familiar to French forces, as many had been supplied as military aid to the Free French as well as Resistance organizations - and it was also a simple and cheap weapon to make.

    In the aftermath of Liberation, there was a lot of political jockeying for power in France. Many different factions had armed themselves during occupation, form the far right to the far left, and everyone wanted to be in a position of power in post-war France. Gnome et Rhône was contracted to make 20,000 of the R-5 submachine guns specifically for the PCF, the French Communist Party (Parti communiste français). The Gaullist government found out about the production and took the guns for itself before any reached the PCF.

    The R-5 (named because it was produced in Limoges, in the 5th Region of France as organized during the Resistance) was parts-interchangeable with the standard British MkII Sten, despite having a number of unique features. The R5 used a barrel 60mm (2.5 inches) longer than the standard Sten barrel, a solid wooden stock of the same shape as the MkII, and a vertical front grip inspired by the Thompson. Although missing on this example, it also had a rotating receiver cover that could be used to lock the bolt in the forward position.

    Of the 20,000 R-5s ordered, only 8,000 were delivered as best we can tell today. They were used by the military within France and also in Indochina and even into Algeria. In the immediate postwar years France was heavily dependent on US and UK war material, but wanted to equip a larger force than the Anglo-American allies were planning to supply. The R-5 made a useful interim weapon while the French arms industry reestablished itself and eventually developed the MAS-49 rifle family and the MAT-49 submachine gun.

    The R-5s were mostly used until utterly worn out, and are extremely rare today. I am grateful for the cooperation of the IRCGN (Institut de Recherche Criminelle de la Gendarmerie Nationale) in having access to film this example for you!

    Právěže nikoho neznám, kdo by měl ComTacy :(

    Já mám Sordiny léta a jsem s nimi naprosto spokojený. Mikrofon či propojení s vysílačkou apod. k nim myslím lze přikoupit, leč potřebu toho jsem nikdy nepocítil; zato střílím z pušky, která mi dobře tvarované Sordiny neodstrčí z ucha. (Což zrovna Tobě bude hádám asi jedno.)

    Nějaké laciné Peltory (tuším cca za 2-3 KKč) jsem míval kdysi dávno, a spokojený jsem s nimi nebyl — tlumily málo, elektronika zdaleka tak dobře vnější zvuky nepředávala, a s pažbou pušky se dost nepříjemně přestrkávaly. Ale tyhle drahé ComTacy vůbec neznám, třeba budou mnohem lepší... přinejmenším by měly mít nominálně větší tlumení než Sordin podle specifikací. Ideálně kdybys našel někoho, kdo je má, mohl si je půjčit a vyzkoušet.
