This video explores budget-friendly AR-9 lower and magazine conversion options, comparing dedicated PSA lowers with adapters like KAK for Colt mags, Torkmag for Glock mags, and Mean Arms Endomag for PMAGs. While Glock mags offer practicality, Colt mags are preferred for aesthetics. The Endomag conversion is flagged for significant safety concerns and reliability issues, making dedicated lowers or the KAK/Torkmag adapters better choices for a budget AR-9 build.

This review explores the EndoMag 9mm conversion for AR-15s, highlighting its cost-effectiveness for training. While it offers a familiar manual of arms and cheaper ammunition, reliability is heavily dependent on the upper receiver. The Faxon Firearms upper performed well, but the FM Products upper experienced significant malfunctions, indicating potential compatibility issues.

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.
