At the Range with the Marlin UD-42 SMG

The Hyde/Marlin M2 is a rare submachine gun positioned between the Thompson and Grease Gun. It's lighter and cheaper to produce than the Thompson, utilizing compatible magazines. Its design incorporates George Hyde's innovative use of metal sintering for complex internal parts, a process involving powdered metal molded under heat and pressure.

The Marlin Model 1917 is a licensed copy of the Colt Model 1895/1914, itself an evolution of the original Colt 'Potato Digger'. It features a unique gas-operated system using a swinging lever mechanism, distinct from typical gas pistons. This lever, when activated by gas tapped from the barrel, cycles the action, earning the 'Potato Digger' nickname due to its violent movement potentially digging into the ground.

The M3 Grease Gun's magazine design was driven by its mass-production, low-cost philosophy, mirroring the British Sten gun. Unlike the Thompson's complex T-lug system requiring milled receivers, the M3 used a simpler single-feed magazine compatible with its stamped sheet metal construction. This design choice prioritized manufacturing efficiency over inter-operability with existing Thompson magazines.

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.
