Q&A 30: ACRs, Besas, and Czechoslovakia

The Steyr ACR was a 1990s bullpup rifle developed for a US military program, notable for its polymer construction and unique flechette ammunition. Firing needle-like projectiles at an extreme 4,800 fps, it featured an open-bolt action and a distinctive ring primer for reliable ignition. While innovative, it represented a departure from conventional firearm design.

This video discusses the potential return of the Magpul Masada, also known as the Bushmaster ACR. The speaker, demonstrating expertise in firearm history and current market trends, notes Magpul's recent social media activity hinting at a revival. The rifle itself is highlighted as a modern firearm that has influenced subsequent designs, with the example shown configured for Designated Marksman Rifle (DMR) duties.

This video features an InRange mud test of the Bushmaster ACR. The description notes the rifle's lineage, from the Magpul Masada to the Remington ACR and finally the Bushmaster ACR, highlighting its brief potential as the future of rifles. The test aims to evaluate the rifle's performance under challenging conditions. The channel's Patreon is also linked for viewer support.

The Bushmaster ACR, while iconic in video games like MW2, is presented as a collector's item rather than a practical modern rifle. Its high secondary market price and the superior performance of current AR-15/M4 platforms make it an expensive nostalgic piece. Key features include a tool-less quick-change barrel and an adjustable gas system, but ergonomics like the bolt release and safety selector are critiqued.

The Bushmaster ACR, originally the Magpul Masada, was designed to improve M4 reliability in harsh conditions. Despite innovative features like a tool-less quick-change barrel and a smooth short-stroke piston system, poor business decisions and a high price point hindered its market success. While mechanically sound and adaptable, it ultimately failed to displace the AR-15.

The ACR, originally the Magpul Masada, is being realized by Templar Precision in Ohio. Chambered in 5.56, it accepts standard AR-15 magazines and features fully ambidextrous controls. Notable aftermarket parts include a Geissele trigger, RPM Tool handguard, and ACC Blastout muzzle device. Its iconic folding stock has influenced many other platforms.

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.
