Semiauto SAR-80 "Sterling Assault Rifle" at the Range

This video provides an in-depth review of the SAR-80, a simplified variant of the AR-18 design originating from Singapore. It highlights the rifle's economical construction, featuring stamped steel receivers, and demonstrates its semi-automatic function during a range test. The review also touches upon its internal components and manufacturing philosophy.

The SAR80, a Singaporean-designed rifle based on the Sterling AR-180, was produced by Chartered Industries of Singapore. It features a stamped steel construction, a short-stroke gas piston system, and accepts STANAG magazines. While adopted by Singapore and exported, it saw limited use in Slovenia, which preferred AK variants. The rifle's design aimed for economical production for export markets.

The Aly & Kaufman AKB-23 is a bullpup conversion kit for the Brownells BRN-180, designed to replicate the feel and ergonomics of the British SA80/L85 rifle. Utilizing the AR-180's mechanical lineage, the kit offers an affordable way to experience the bullpup platform. It features a milled aluminum lower and 3D-printed furniture, with assembly requiring integration of the BRN-180 upper. Performance is noted as reliable, providing an authentic handling experience.

The AR-180, designed by Arthur Miller as a cost-effective stamped-steel alternative to the M16, utilizes a short-stroke piston system. Despite its 'guerrilla warfare' reputation and appearance in pop culture like 'The Terminator,' it failed US military testing due to reliability issues. While a unique collectible, its performance and proprietary parts make it unsuitable as a modern tactical carbine.

The ArmaLite AR180, though a commercial failure and rejected by the US military, boasts an incredible legacy due to its innovative short-stroke gas piston system. This design, intended as an affordable alternative to the AR-15, influenced numerous modern firearms, including the British SA80/L85 series. Despite its 'crude' reputation, the AR180 proved to be a reliable and well-shooting rifle.

This video reviews the rare ArmaLite AR-180 Police Carbine, a compact variant of the AR-18 designed for economy and easier manufacturing. It highlights the carbine's stamped receiver, short-stroke gas piston system, and unique 10.5-inch barrel with a conical flash hider. The review details its limited production by Sterling in England, specific serial number prefixes for variants, and its current status as a highly sought-after collector's item due to extreme rarity.

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.
