SIG 550 / Stgw 90: The Swiss Kalashnikov

This "Swiss Rifle Showdown" compares the classic SIG 550 against the modern B&T APC-223. The SIG 550, a reliable long-stroke piston rifle, is a rare collector's item. The APC-223 offers superior modularity, a short-stroke piston, hydraulic buffering for reduced recoil, and easier suppressor integration, making it a more accessible, modern option.

The SIG 550 (Stgw 90) is presented as one of the finest service rifles ever produced, lauded for its exceptional Swiss engineering, accuracy, and reliability. The review highlights its cold hammer-forged barrel, long-stroke gas piston system, and unique winterization features designed for extreme conditions. Garand Thumb emphasizes its superior fit, finish, and quality control, making it a benchmark in combat rifle design.

The SG 550 (Stgw 90) demonstrates exceptional practical accuracy, achieving a perfect score at 500 yards with iron sights. Its Swiss-designed diopter sights and adjustable two-stage trigger contribute to its precision. The rifle's lineage traces back to a SIG-Beretta collaboration, evolving into the standard Swiss Army rifle known for reliability and accuracy.

This video features a review of the Swiss Arms SG 751 SAPR rifle, chambered in 7.62x51mm. The reviewer highlights the rifle's Swiss origin and its distinct Russian AK DNA. The description also points to other related videos on the SIG 550 and the SG 751 SAPR from the "Mishaco" channel, and promotes the "AKOU" channel's store. It's a detailed look at a unique firearm with an interesting heritage.

This video provides a detailed look at the Swiss Sig 550/Pe90 rifle, showcasing its mechanical operation and live-fire performance. The review highlights the rifle's smooth action, the unique translucent polymer magazine, and its reliability during rapid-fire sequences. It emphasizes safe firearm handling and appropriate gear usage during the outdoor range demonstration.

This video tests the magazine compatibility of the Sig 550 rifle with standard AR-15 PMAGs. The demonstration clearly shows that the Sig 550 does not natively accept AR-15 magazines, as the PMAG fails to lock into the magwell. Modifications or different lower receivers would be required for such compatibility.

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.
