Steyr M30S Prototype: A Repurposed WW1 Improved Mauser

This guide details the complete disassembly of a Mauser rifle bolt, specifically the 'cock on open' type. It covers removing the bolt, separating components like the bolt body, extractor, firing pin, shroud, and safety. The video also addresses common issues causing light strikes, such as headspace, debris, or weak springs, and provides reassembly instructions.

This guide details the essential preparation steps for installing a new bolt handle on a Mauser bolt, as demonstrated by Larry Potterfield. It covers marking the cutoff line on the original bolt, carefully removing the old handle with a grinder, and precisely shaping the new handle using a protractor and file. This meticulous prep work is crucial for a successful weld.

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.
