Steyr ACR: A Polymer Flechette-Firing Bullpup From the 90s

This video features firearms expert Jonathan Ferguson examining a rare and 'cursed' bullpup mock-up of the Armalite AR-18. The prototype is characterized by its unconventional design, including a lack of trigger linkage, mismatched receiver parts, crude welds, and an unusual front sight arrangement, making it more suited for a video game than actual combat. The discussion also briefly touches upon the SA80 as a point of comparison for bullpup designs.

Amber and Doshie from Exile Armory showcase a wide array of new firearms and accessories. The video features various pistols, rifles, shotguns, and suppressors from brands like FN, Q, Bergara, Springfield Armory, and Beretta, with detailed pricing and some technical specifications provided. The presentation is casual and informative, highlighting new inventory for customers.

The Steyr AUG (StG 77) is a revolutionary bullpup rifle featuring an integrated 1.5x optic and extensive polymer construction. Its progressive trigger allows for both semi-automatic and full-automatic fire with a single trigger pull. The rifle also boasts a quick-change barrel system and a fully polymer fire control group.

The FAMAS G1 is a simplified export variant of the French FAMAS rifle, featuring a redesigned polymer lower receiver integrating the pistol grip and trigger guard. Production was streamlined by removing features like grenade rings, grenade sights, and slide-up night sights. These changes aimed to reduce manufacturing complexity and cost for international markets.

The S.R.E.M. (Sniper Rifle Experimental Model) was a unique British bullpup sniper rifle prototype from WW2, featuring a pistol grip that doubled as a charging handle to maintain sight picture during cycling. Only two were commissioned, and this is the sole surviving example. Its action utilizes a simple two-lug rotating bolt locked by a pin mechanism.

The Armi Jager AP85 is an Italian-made .22 LR rifle mimicking the FAMAS bullpup design, but internally based on Armi Jager's AK-style action. It features a mix of stamped steel, wood furniture, and cast aluminum, utilizing AK-pattern .22 magazines. Production ceased in the early 1990s, making these rifles scarce and parts difficult to find.

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.
