A Shorter Stoner: The BRN-180s

The Brownells BRN-180 upper receiver offers a modern adaptation of the classic AR-18/AR-180 design, featuring a short-stroke gas piston system and dual internal recoil springs. This design eliminates the need for a buffer tube, enabling the use of folding stocks and compatibility with standard AR-15 lower receivers. It aims to provide improved reliability by keeping fouling out of the receiver, making it a practical and enjoyable firearm for various uses.

The ArmaLite AR-180, despite its 'janky' stamped steel construction and simple iron sights, demonstrated surprising practical accuracy, achieving around 2 MOA at 500 yards. Eugene Stoner designed it as an affordable alternative to the AR-15, utilizing a robust short-stroke piston system that became the foundation for modern designs like the G36 and SA80. The rifle's historical association with the IRA and 'The Troubles' is noted, but the review focuses on its technical performance and legacy.

This video features a practical accuracy test of the BRN-180 (Gen2) in an SBR configuration, pushing its capabilities to 500 yards on a windy day. The review highlights the collaboration between Brownells and Primary Weapons to modernize the AR-180 platform. It also encourages viewers to support the channel through various platforms and mentions a discount code for Slate Black Industries.

This video reviews the BRN-180 by Brownells, highlighting its execution as a retro clone inspired by the AR-18. The reviewer discusses the AR-18's origin as a piston-driven AR and notes the modern enhancements Brownells has incorporated into the BRN-180, such as billet receivers, improved barrel steel, and an adjustable gas system. The video aims to showcase this modern iteration of a historical firearm design.

This video analyzes the Brownells BRN-180, detailing its evolution from the AR-18 and AR-180 platforms, and also touches upon the Armalite AR-180B. The description lists several accessory products, including Vortex Optics, Magpul sights, and cleaning supplies, suggesting the video may cover the integration and functionality of these items with the firearm. The content appears to be an in-depth review or historical comparison focused on the AR-18/180 lineage and its modern interpretation.

This video introduces the new Brownells BRN-180S™ upper receiver, a short-barreled variant of the acclaimed BRN-180™. Featuring a 10.5" barrel, it's designed for AR pistol or SBR builds. A key feature is its adjustable gas system, allowing for easy switching between suppressed ('S') and unsuppressed ('U') operation, developed in collaboration with Primary Weapon Systems (PWS) and FM Products. The video also includes a brief overview and disassembly of the AR-180 operating system.

This video features a former Navy SEAL, Jeff Gonzales, providing expert feedback on a home defense AR-15 build. He critiques the rifle's accessories, particularly the sling, and emphasizes the importance of reliable optics and the benefits of a suppressor for indoor use. The discussion highlights practical considerations for effective home defense firearms.

The Beretta ARX-160, showcased at SHOT Show 2011, is a modular, piston-driven rifle featuring ambidextrous controls and tool-less disassembly. Its design emphasizes adaptability with multiple sling points, interchangeable magazine releases, and a quick-change barrel system. While currently limited to military/defense use, future law enforcement and civilian variants are planned.

Fostech unveiled a 20-round .50 BMG drum magazine for Barrett M107 and 82A1 rifles, constructed from billet machined aluminum. They also introduced the Fostech Rader, a lightweight .308 rifle featuring a proprietary magnesium aluminum alloy and ambidextrous controls. The drum mag is priced at $1599 with a Q3/Q4 availability, while the Rader rifle is expected around $3000 with a Q4 release.

Testing a Remington 158gr SJHP .357 Magnum load from a 16-inch Rossi M92 reveals impressive performance, achieving 1709.6 fps. The round exhibited significant fragmentation and penetration of 20.1 inches in ballistic gel, behaving more like a rifle cartridge due to its velocity. This challenges typical handgun round terminal ballistics expectations.
