Why Did The US Military Choose This Tiny SMG?

The CBJ-MS is a modernized 9mm submachine gun based on the Swedish K, designed as a compact PDW-style platform. It features a unique progressive trigger for semi and full-auto fire without a selector, a grip safety, and a vertical foregrip that stores a spare magazine. The muzzle is compatible with standard M16 bipods for added stability.

The MP5SD is an integrally suppressed submachine gun that uses a ported barrel to slow 9mm rounds below the speed of sound, achieving exceptional quietness. While accurate and smooth due to its roller-delayed blowback system, it requires frequent maintenance due to carbon buildup. Its stealth capabilities are remarkable, with downrange reports being nearly imperceptible.

Gearhead Guns is producing a Type 100 Nambu PCC recreation, with the first batch shipping around March. It's available in 9mm Parabellum with 9-inch or 16-inch barrel configurations for SBR compliance. Customization options include various metal and wood finishes, with optional bayonet lugs.

This comparison between the MP-40 and PPSh-41 highlights differing design philosophies. John Keene favors the MP-40 for its ergonomics and adaptations for higher magazine capacity, while Ian McCollum prefers the PPSh-41 for its high rate of fire and semi-auto selector. Both speakers acknowledge the controllability of their preferred weapon despite its characteristics.

This video showcases the HK MP5-N submachine gun with a suppressor attached. It highlights the firearm's modularity, demonstrating suppressor attachment and the iconic 'HK slap' for chambering rounds. The live fire segment emphasizes the suppressed MP5-N's manageable recoil and quiet operation during rapid fire and tactical reloads.

This video focuses on the B&T KH9 Covert, a folding submachine gun. The content likely explores its features, design, and potential applications, with an emphasis on its compact and concealable nature. It is aimed at firearm enthusiasts interested in niche or specialized firearms.

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.
