The Radical Firearms RPR CA-Compliant in 5.56 NATO (MPN FR16556SOC15RPRCAB5) is an AR-15 pattern rifle built for California-compliant configurations, pairing a 16-inch black Melonite steel threaded barrel with a 1:7-inch twist and a black anodized aluminum receiver with a Picatinny rail. Radical Firearms fits this rifle with a 15-inch M-LOK handguard, a B5 Systems Type 23 pistol grip, and an A2 flash hider. The rifle feeds from a 10+1 capacity fixed-configuration magazine sized for state compliance. Among AR-platform rifles in the AR rifles category, the RPR CA-Compliant favors shooters in states with magazine-capacity restrictions who still want a full-featured 5.56 AR-15.
