Colette Gravity Pistol

This review details the rare 11mm Devisme centerfire revolver from the 1850s, a high-end Parisian firearm. It highlights the unique gear-driven ejector, bottom-break action, and cylinder drag spring. The revolver's mechanical similarity to earlier percussion models and its limited American Civil War use are also discussed.

The Guycot Chain Pistol, patented in the 1870s, is a rare 40-shot, double-action firearm utilizing caseless 'Rocket Ball' ammunition. Its complex mechanism involves a reciprocating barrel for sealing and a cycling chain of chambers. Despite its high capacity, the underpowered .25 caliber rounds made it unsuitable for military use, contributing to its rarity with only a few hundred produced and a dozen surviving.

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.
