Stamm-Saurer Model 1913 Long-Recoil Prototype Rifle

This guide details the proper cleaning and maintenance procedure for the Desert Eagle pistol, as demonstrated by The VSO Gun Channel. It covers disassembly, cleaning of critical components like the barrel, chamber, and rotating bolt, and reassembly with lubrication. The host emphasizes the unique operation of the Desert Eagle and the importance of using specialized cleaning solvents and lubricants for optimal performance.

This video provides a detailed technical breakdown of the AK platform's operating system, focusing on the long-stroke gas piston and rotating bolt mechanism. Brandon Herrera uses a Russian Saiga Legion in 7.62x39mm to illustrate how the firing sequence, locking system, and gas operation contribute to the AK's legendary reliability. The explanation covers the entire cycle of operation from firing to ejection and reloads.

This video provides an in-depth look at the Norinco Type 97 NSR, the Canadian semi-auto export version of the Chinese QBZ-95. It details the rifle's mechanics, including its short-stroke gas piston system and rotating bolt, and walks through a complete field stripping procedure. The discussion also covers the historical context of Chinese cartridges and the ergonomic considerations of the bullpup design.

This entry details the Mauser 1902 Prototype Long Recoil Rifle, a rare experimental firearm from Paul Mauser's quest for a successful self-loading rifle. It explains the mechanics of the long recoil system, comparing it to other firearms like the Browning Auto-5 and Remington 8. The prototype's history, including its failure during German Army testing due to extraction issues and its subsequent sportorization, is also covered.

This guide outlines the comprehensive manufacturing and assembly process for the Beretta A400 semi-automatic shotgun, as detailed by Beretta's own manufacturing experts. It covers everything from initial parts inspection and internal component assembly, including the unique gas system and rotating bolt, to rigorous quality control, proofing, and final reliability testing. The process highlights Beretta's commitment to engineering excellence and efficient, reliable firearm production.

This video details a rare Snabb semi-automatic conversion of a Dutch Mannlicher bolt-action rifle, developed in the late 1930s by Swedish inventor Arenberg. The complex gas-trap system, featuring intricate ratcheting teeth and multiple springs, aimed to provide budget-friendly semi-automatic firepower for mid-sized nations. Despite its innovative approach, extreme mechanical complexity made it difficult to maintain, preventing military adoption.

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.
