The Radical Firearms RPR SOCOM Gray 5.56 NATO rifle (Radical Firearms part no. FR16-5.56SOC-15RPR-GRY) pairs a 16-inch SOCOM barrel with a 15-inch free-float RPR handguard and Grey B5 Systems furniture. Forged 7075-T6 receivers sit under a mid-length gas system, which smooths the cycling of 5.56 NATO ammunition. The Bravo stock and Type 23 pistol grip are both B5 Systems parts, chosen for comfort and control. It is a straightforward AR for range days, ranch use and modular builds. Gray furniture sets it apart from the other colors in the line.
