Radical Firearms FR16556SOC15Rpr 5.56 NATO 16in Melonite 15in M Lok

The Radical Firearms FR16556SOC15RPRCAB5 RPR is a California-compliant AR-15 built for shooters who demand a reliable, adaptable semi-auto rifle for range training, target shooting, competition, and duty-style applications, featuring a 16" Black Melonite steel threaded barrel with a 1:7" twist that stabilizes heavier 5.56 NATO projectiles and resists wear from high-round-count use. The black anodized aluminum receiver pairs with a 15" M-LOK handguard and full-length Picatinny rail to give you mounting real estate for optics, backup sights, lights, and slings while keeping weight and balance centered for rapid follow-up shots; the mil-spec trigger and right-hand configuration offer a familiar AR feel for most shooters. The RPR series from Radical Firearms focuses on practical reliability and modularity, and this model's A2 flash hider and CA-compliant features meet state regulations without sacrificing function. With a threaded muzzle for muzzle devices or suppressor mounts, steel barrel construction, and standard AR ergonomics, this rifle is an excellent platform for customization, competitive builds, tactical training, and serious range work where durability and consistent accuracy matter.
