Radical Firearms RF-15 RPR AR Pistol, 5.56 NATO, 7.5-Inch

The Radical Firearms RF-15 RPR AR pistol in 5.56x45mm NATO (brand part no. FP7.5-5.56M4-7RPR) pairs forged mil-spec upper and lower receivers with law-enforcement-grade fit for a duty-ready pistol build. Radical Firearms treats the 4140 chromoly vanadium steel barrel with a Melonite finish for hardness beyond chrome lining, and carries that same treatment through the bolt carrier group to cut wear and boost reliability. The 7-inch RPR free-float handguard uses M-LOK slots on the sides and bottom, keeping hands clear of the barrel and opening up rail space for lights and grips. Among AR pistols built for compact, maneuverable use, this RF-15 configuration favors home defense, range work, and truck-gun duty.
