Union Automatic Revolver

This expert-level guide details the field stripping process for the rare Reifgraber .38 S&W Automatic Pistol, as demonstrated by Ian McCollum. It covers the removal of the fire control group, barrel, and bolt assembly, highlighting the unique short recoil system with gas assist. The video provides a deep dive into the mechanics of this early 20th-century design.

This expert-level examination of the Webley-Fosbery Automatic Revolver, presented by Brownells, details its unique recoil-operated semi-automatic action, a significant innovation for its time around 1900. The review highlights its historical context as a potential military sidearm, its availability in calibers like .455 Cordite and .38 Automatic, and its popularity in competitive shooting due to its soft recoil and consistent single-action trigger.

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.
