The Rock River Arms LAR-15M RRAge 10.5-inch pistol from Rock River Arms (brand part no. DS2142) brings a longer barrel to the RRAge pistol line. A 10.5-inch chrome moly barrel with a 1:9 twist and an A2 flash hider on 1/2-28 threads sits under a 7.25-inch RRAge aluminum free-float M-LOK handguard. Rock River fits an SB Tactical adjustable stabilizing arm brace, and the pistol measures 28 inches extended and 26.25 inches collapsed at 5.7 pounds. The 5.56 NATO chamber also fires .223 Remington. It suits shooters who want a bit more barrel than the 7-inch pistol while staying compact.
