Magic Gunsmithing Box Experiment #1

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 video presents a challenge from Forgotten Weapons, where the expert instructor is unable to disassemble a Madsen 1945 pistol. He outlines common disassembly methods for other firearms like the Colt 1903 and Ruby pistols, noting the Madsen's barrel knurling suggests a rotational release. However, the only visible mechanism, a spring plunger, only locks the slide partially open, leaving the full disassembly process a mystery.

This guide details the process of replacing a faulty extractor on a 2011-platform handgun, specifically addressing recurring extraction failures experienced with the Bul Armory SAS II Ultralight. The video demonstrates the installation of an Atlas Gunworks extractor, a common aftermarket upgrade for 2011s, and highlights the importance of proper tensioning for reliable firearm function. The speaker, an experienced firearms instructor, provides practical advice based on extensive troubleshooting and range testing.

This expert-level guide details the assembly and disassembly of the Ruger Red Label III over/under shotgun. It emphasizes safety protocols, including ensuring the firearm is unloaded and wearing safety glasses. The process involves separating the receiver/stock from the barrel/fore-end, with specific instructions for fore-end removal and reattachment. Crucially, it highlights the need to fully move the top lever right before barrel installation to avoid damage, followed by a function check of the safety and barrel selector.

This guide provides expert-level instructions for cleaning the Ruger Red Label III Over/Under Shotgun, drawing from a Ruger Firearms Tech Tip. It details a comprehensive step-by-step process for disassembly, cleaning individual components like the bore, choke tubes, receiver, and fore-end, and proper reassembly. The guide emphasizes critical safety precautions throughout the procedure, including the use of safety glasses and ensuring the firearm is unloaded.

This guide details the reassembly process for the Ruger 10/22 Rifle, presented by a Ruger firearms instructor. It emphasizes safety precautions, including the removal of ammunition and the use of safety glasses. The steps cover the reinstallation of the charging handle, bolt, receiver plug, bolt stop pin, and fire control group, followed by stock attachment and action screw tightening. Crucially, it concludes with essential function checks to ensure proper operation.

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.
