The Fastest 380 SMG in the world; the Gold MAC-11

The Walther MPK and MPL are post-WWII submachine guns developed in the late 1950s and produced from 1963, competing with the Uzi and MP5. They feature a simple stamped sheet metal construction, ambidextrous controls, and a manageable 550 RPM rate of fire. While robust and portable, their sights are considered a weak point by the reviewer.

Hank Strange provides an expert review of the M3 Grease Gun, highlighting its unique manual of arms, including the internal crank-style charging handle. He demonstrates its operation and live fire, noting its 'humming like a sewing machine' cyclic rate and historical context as a 1943 suppressive fire weapon. The review emphasizes the importance of understanding its specific loading procedure.

The CBJ-MS is a modernized Swedish submachine gun designed by Bertil Johansson, aiming for rugged durability over polymer PDW fragility. It features a unique muzzle sleeve for bipods, a forward grip with magazine storage, and a progressive trigger. The design draws inspiration from the Swedish K for reliability and utilizes a telescoping bolt similar to the Uzi, allowing for a compact receiver made from stamped stainless steel.

This YouTube video title, "SMG barato e top para quem tá com pouca grana!" (Cheap and top SMG for those with little money!), suggests a review or recommendation of an affordable submachine gun. The focus is on providing value for budget-conscious buyers, likely targeting individuals looking for a capable firearm without a high price tag. The content probably involves showcasing the SMG, discussing its features, performance, and overall suitability for various applications, with an emphasis on its cost-effectiveness.

This video explores the Warhammer Armaments Forced Reset Trigger (FRT) for MP5 and MP5K platforms, enabling semi-automatic variants to achieve extremely high rates of fire, exceeding factory full-auto speeds. The FRT's mechanical design allows for rapid follow-up shots by using the bolt's forward movement to reset the trigger, while legally remaining semi-automatic. The review also covers the use of Lee Sporting lower receivers for AR-style triggers and improved ergonomics, and the impact of suppressors on cyclic rate.

The GForce Arms Jawbone is presented as a highly affordable American-made AR-9 platform firearm, retailing between $350-$400. It features a side-charging upper, a monolithic grip with integrated magazine storage, and can be enhanced with aftermarket parts like an SB Tactical brace and a Rise Armament trigger. The reviewer found it reliable with zero jams during testing and described it as accurate and enjoyable to shoot.

This video demonstrates the proper technique for loading the M1 Garand to prevent 'Garand Thumb'. It emphasizes maintaining downward pressure on the top round to control the bolt's cycling. The content debunks the idea that 'Garand Thumb' is inevitable, attributing it to inexperience and improper handling.

The Altyn helmet, a Russian titanium model, is tested for its ballistic capabilities. While effective against 9mm NATO and 00 buckshot, it fails to stop rifle rounds like 5.56x45mm and .308 Winchester. The visor cracks under birdshot impact. Despite its historical reputation, its extreme weight and lack of rifle protection make it outdated compared to modern composite helmets.

This ballistic test by Garand Thumb reveals that NIJ Level 3A rated ballistic masks, while stopping some projectiles, fail to adequately protect the wearer due to extreme backface deformation. Hits from a .44 Magnum caused fatal deformation, and rifle rounds completely penetrated. The conclusion is that these masks are largely ineffective and potentially dangerous, recommending helmets and proper training instead.

This video delves into the notorious 'Garand Thumb' phenomenon, explaining its mechanics and pain level through direct testing. It covers the M1 Garand's history, technical specifications, and proper loading techniques to avoid injury, including the 'bladed hand' method. The content also features novice testing and concludes with advice on training and firearm ownership.
