Bushmaster Assault Rifle: A Stoner-Inspired 70s Carbine

The Stoner 63 system, designed by Eugene Stoner, was a highly modular firearm capable of multiple configurations including rifle, carbine, and various machine guns. Initially developed as the Stoner 62 in 7.62 NATO, it was scaled down to 5.56mm as the Stoner 63. Despite its innovative design and light weight, particularly favored by the US Navy SEALs as the Mk23, it suffered from reliability issues and high maintenance requirements in demanding environments like Vietnam.

This video provides an expert-level overview of the Stoner 63A, a revolutionary modular weapon system designed by Eugene Stoner. It details the weapon's history, its development from the Stoner 62, its unique modularity allowing conversion between rifle, carbine, and machine gun configurations, and its operational use, particularly by Navy SEALs. The presenter, Ian McCollum, demonstrates the disassembly process, highlighting the simple pin-based system for quick component changes.

This video offers a rare glimpse at an original Stoner 63A, manufactured by Cadillac Gage and discovered in Turkey. The host highlights its modular design and historical significance as a piece of American firearms history. A future video on the Rob Arms M96 rifle is teased.

This review explores the historical Stoner 63A rifle system and its modern revival as the Robinson Armament M96. It highlights the original's modularity, including its use by US Navy SEALs in Vietnam, and the M96's attempt to bring back the design during an 'assault weapon' ban. The video features a live-fire demonstration of the M96 in its unique top-fed 'Bren' configuration.

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.
