Slovenian SAR80: Sterling Out-Simplifies the AR-180

This review covers the SAR-80, a simplified semi-automatic rifle based on the AR-18, originally designed by Sterling and later produced by Chartered Industries of Singapore. The video highlights its simple stamped steel construction, short-stroke gas piston system, and pleasant shooting characteristics during a range test. It also details US semi-auto rebuilds by TTE Precision Metalworks, noting compatibility with AR-15 magazines.

The Armalite AR-18 and AR-180 are explored as budget alternatives to the AR-15, featuring stamped sheet metal construction and a short-stroke gas piston system. Despite a commercial failure for Armalite, the design influenced numerous modern military rifles like the G36 and SA80. Production was licensed to Howa in Japan and Sterling in England, with variations in markings and serial numbers distinguishing manufacturers and full-auto capabilities.

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.

Alyssa Seymour provides an in-depth look at the B&T KH9S, a modern submachine gun drawing inspiration from iconic WWII and Cold War designs like the Sten and Sterling. The review highlights its unique side-feeding magazine, top-mounted charging handle, and tri-lug barrel for suppressor compatibility, emphasizing its heritage and modern features.

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 from Military Arms Channel explores the Masterpiece Arms MPAR, a rifle that is a clone of the Australian Leader T2 Mk5, which itself was a clone of the original Armalite AR-18. The description provides a detailed history of the AR-18 design and its evolution through various manufacturers and countries. It also includes links to the MAC website, Patreon, Utreon, Modern Gun School, Discord, Twitch, and discount codes for Primary Arms and Challenge Targets. The video is a deep dive into the lineage and development of this particular firearm platform.

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.
