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

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.

This video explores the Stamm-Zeller 1902, a unique Swiss straight-pull rifle that was notably converted into a semi-automatic firearm. The content likely delves into the historical context of this prototype, its design features, and the modifications made to transform its action. It promises to be an interesting look at a less common piece of firearms history, particularly for those interested in Swiss military arms and early semi-automatic development.

The SR-88A represents Singapore's evolution of the AR-18 design, featuring a milled aluminum lower receiver and a long-stroke gas piston system. It utilizes AR-pattern magazines and has a proprietary optics rail. While not produced in massive numbers, it saw service in Singapore and Slovenia.

The Pioneer Arms PM-63C Rak, a semi-auto conversion of a Polish PDW, was tested in a BUG match. Despite initial concerns about reliability and a challenging trigger and sights, the firearm performed better than expected, finishing 8th overall. The high bore axis contributes to significant muzzle flip, and the unique ejector mechanism integrated into the magazine can cause issues during competition.

The Demro XF-7 Wasp is a 1970s open-bolt, semi-automatic carbine available in 9mm and .45 ACP, featuring a unique caliber conversion system using Sten or M3 Grease Gun magazines respectively. Its design evolved from earlier Fox and Eagle carbines, and it includes integrated tools in the stock. Production ceased in 1983 due to an ATF ruling on easily convertible firearms.

This video showcases the Browning Maxus II, a 12-gauge semi-automatic shotgun designed for a wide range of shooters. The review highlights its upgraded features, including the SoftFlex cheekpad and Inflex recoil pad for enhanced comfort, oversized controls for improved operation, and a revised styling. It also details the gas-operated Power Drive system for smooth shooting, the Lightning Trigger for speed and crispness, and practical features like Speed Load Plus, Nickel Teflon coating, chrome chamber and bore, a magazine cut-off, and a lightweight magazine tube. The video also briefly introduces Browning's Wicked Blend waterfowl shotshells, a mix of steel and bismuth.

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.
