Evolving the Cheek Pistol Concept: Calico M950

This review re-evaluates stockless shotguns like the Mossberg Shockwave and Remington Tac-13, initially deemed 'mostly useless' by the reviewer. Through structured testing using a 'cheek pistol' technique developed by Rhett Neumayer, the performance in speed and recoil control was found to be nearly on par with traditional stocked shotguns for home defense. While shooter fatigue is a drawback, the semi-auto Tac-13 is recommended for its ease of use.

This video showcases an updated Keltec CP33 configured as a 'cheek pistol'. Key modifications include a custom 3D-printed cheek rest for improved optic acquisition and an Otterman Outdoor spare magazine holder, increasing total capacity to 66 rounds of .22 LR. The build emphasizes enhanced ergonomics and sustained fire capability.

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.
