Patchett Machine Carbine Mk I: Sten Becomes Sterling

The L2A3 Sterling SMG, developed by George Patchett, replaced the Sten gun with a lighter design and slower rate of fire. It featured a unique curved magazine with roller followers, a folding stock, and a double mainspring system for improved accuracy. The 9mm Sterling served British forces for nearly 40 years, proving reliable in conflicts like the Falklands War.

The Australian F1 SMG, adopted in 1962, was designed to replace the Owen gun, aiming for cheaper production while retaining its top-mounted magazine. It features a progressive trigger for semi-auto and full-auto fire, a non-reciprocating charging handle, and uses Sterling magazines. While functional, its offset sights and perceived fragility compared to the Owen gun are noted drawbacks.

This review details the evolution of British submachine guns, starting with the Lanchester as a MP28 copy and progressing to the mass-producible Sten series. It highlights the Sten's cost-effectiveness and reliability issues, contrasting it with the more refined Mark V. The video also covers experimental designs and concludes with the Sterling L2A3, praised for its innovative magazine design and long service life.

This video is a book review of 'The Sterling Years' by James Edmiston, focusing on the Sterling submachine gun and the company's history under Edmiston's ownership. The book covers the design and features of the Sterling SMG, its unique magazine, and provides insights into arms manufacturing during the 1970s and early 80s. It also touches on topics like H&K's marketing strategies, the complexities of gun factory ownership in France, an unusual personal anecdote, the Singapore arms industry, and details of the SA-80 development. The review highlights the book's value for understanding the origins of firearms.

This review explores a modernized semi-automatic Sten Mark V build, highlighting its historical context as a low-cost WWII emergency weapon. Despite improvements like Picatinny rails and a moderator, the 'Future Sten' faces reliability issues, particularly extraction failures, attributed to the inherent challenges of semi-automatic tube gun conversions. The video also critiques the Sten's original magazine design and compares its size to other historical SMGs.

This review of the Sterling SMG highlights its compact and portable design, featuring a reliable 34-round magazine designed by George Patchett. While the light weight can cause muzzle climb, the aperture sights and semi-automatic mode aid accuracy. The video demonstrates traditional hip-shooting techniques and praises the gun's overall handling and historical significance.

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.
