S.R.E.M.: Britain's Experimental WW2 Bullpup Sniper

The Australian Owen SMG, despite its unconventional appearance, is highlighted as an exceptionally reliable submachine gun, particularly effective in harsh conditions. Its unique design features include a bottom ejection port, a top-mounted magazine with an integrated ejector, and a 'hygienic' internal mechanism protected by a firewall. The Owen SMG offers safe, semi-automatic, and full-automatic firing modes, making it a significant piece of World War II military history.

The S.R.E.M. was an experimental British WWII bullpup sniper rifle designed to allow cycling without disturbing the sight picture. It featured a BESA machine gun-inspired mechanism where the pistol grip acted as the charging handle, and was chambered in 8mm Mauser. Despite 22 prototypes being commissioned, only two were completed before the project was canceled in 1945.

This review examines Haenel's simplified StG45(H) prototype, designed to reduce manufacturing costs through extensive use of stampings. Key modifications include relocating the recoil spring to the top of the receiver and a simplified bolt carrier design. While intended for mass production, the actual functional performance of this specific prototype remains undocumented.

This review delves into the rare Schmeisser MK-36,II, highlighting its unique mechanical features and historical connection to the MP40. Key insights include its unusual left-side bolt handle, right-side ejection, and a novel magazine safety mechanism that prevents bolt opening without a magazine. The separated firing pin design is noted as a precursor to the MP38's mechanics, showcasing Schmeisser's innovative contributions to submachine gun development.

The Japanese Type 4 rifle is a World War II-era attempt to replicate the American M1 Garand, chambered in 7.7mm. It features a 10-round box magazine fed by stripper clips, deviating from the Garand's en-bloc system. While mechanically similar to the Garand, it incorporates Japanese design elements like an Arisaka-style sling swivel and a tangent rear sight, which is criticized for its small aperture.

The Bren MkI is highlighted as a feature-rich light machine gun from World War Two, notable for its stabilization handle and innovative 30-round magazine design that prevents rim lock. Its operating mechanism fires from an open bolt, utilizing a gas piston system for cycling. The fire selector offers automatic, semi-automatic ('Repetition'), and safe modes, with a dust cover protecting the magazine well.

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.
