This expert-level guide details the disassembly of the rare Terni Model 1921, presented by Ian McCollum of Forgotten Weapons. The process involves removing the buttstock and trigger guard, analyzing the trigger mechanism including the disconnector, and detaching the front end assembly with its unique monopod and bayonet mount. The video highlights the firearm's simple internal structure and points out a missing component for full-auto functionality.

This guide details the comprehensive restoration process for a 3-inch M5 Anti-Tank Gun and its M6 carriage, as demonstrated by Dylan from Ordnance.com. The process involves meticulous disassembly, addressing seized components with heat and oil, functional testing of mechanisms, and a final preparation for cosmetic restoration including blasting, priming, and painting. The expert emphasizes documentation and a systematic approach to ensure all parts are functional before final aesthetic treatments.

This video details the Indonesian rebore process of 6.5 Dutch Mannlichers to .303 British, utilizing original barrels bored out and re-rifled. It highlights the compatibility of .303 cartridges with the original 6.5 Dutch en-bloc clips and explains the 'double shoulder' effect on spent brass as a harmless artifact of the conversion, serving as an identifier.

This guide details the field stripping process for the Italian TZ-45 SMG, as demonstrated by Forgotten Weapons. Key components like the stamped receiver pieces, charging handle, and their functional interactions, including dust cover capability, are explained. The process emphasizes understanding how the front sling swivel and muzzle nut secure the receiver components.

Mark Novak, a recognized expert in historical firearm restoration, details the complex cleaning and reassembly process for a rare Mauser C96 Schnellfeuer. The guide emphasizes the challenges of cosmoline removal and the critical importance of handling unique, hard-to-find parts for the full-auto variant. It covers internal mechanism analysis, component identification, and essential safety checks during reassembly.

This video provides a basic overview of handling a milled AK47, demonstrating key components like the charging handle, safety selector, and magazine release. It also includes a brief demonstration of partial disassembly, specifically removing the dust cover and recoil spring assembly. The content is presented in a casual, ASMR style.

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.
