ATF Introducing eForm 4 w/ Electronic Fingerprints in December 2021

This ATF update from Forgotten Weapons details a significant recategorization of approximately 4,000 pre-May dealer sample machine guns, making them fully transferable. The National Firearms Act (NFA) and the Firearm Owners' Protection Act (FOPA) were instrumental in this change, which allows many previously restricted HK models to become transferable. Additionally, NFA transfer processing times have drastically improved, with eForm submissions now taking as little as one week, a substantial reduction from previous nine-month waits. However, multi-person trust forms still require manual review and may experience longer delays.

This video details the unique 'French Finger Trap' issue with the MAS-36 rifle's bayonet, where two rifles can become unintentionally locked together. A 1951 French arsenal memorandum identified this problem, proposing a simple modification to the bayonet handle. Drilling a small hole allows a tool, like a firing pin, to depress the internal spring, enabling the separation of locked rifles.

The M134 Minigun is a scaled-down 7.62 NATO rotary cannon, requiring 24V DC power and consuming 1.5 kW. Its high rate of fire (3,000+ RPM) is essential for aircraft engagement windows. The complex delinker mechanism is critical for feeding ammunition, and practical hand-held use is impossible due to weight and recoil. Live fire demonstrates rapid ammunition consumption and the need for indirect aiming.

The H&K G11 is a revolutionary prototype assault rifle designed in the late 20th century, notable for its caseless ammunition and unique rotating drum bolt mechanism. Despite advanced features like a 2000 RPM burst fire rate and integrated optics, its development was ultimately halted by geopolitical shifts and cost concerns.

This video demonstrates the assembly and live-fire of the German 1936 pattern light mortar (L.Gr.W.36). It highlights the mortar's leveling mechanism for accuracy and the difficulty in visually tracking its 50mm projectiles after firing. The content showcases historical military hardware and its operational use.
