The Rock River Arms LAR-15M RRAGE (brand part no. BLK2142) is a .300 AAC Blackout AR-pattern pistol, built on a 10.5-inch threaded barrel with an SB Tactical SBA3 adjustable brace rather than a shoulder stock. It pairs a low-profile gas block with a single-stage trigger and a lightweight, free-floating 7.25-inch M-LOK handguard for a compact, easy-to-run package. It suits shooters who want a maneuverable .300 Blackout pistol for home defense or suppressed use. The A2 flash hider rounds out a well-equipped, ready-to-run build.
