Radical Firearms RPR Features The Radical Firearms RPR is built around Mil Spec upper and lower receivers finished in black anodized aluminum giving the rifle a proven foundation that interfaces with standard AR-15 parts and accessories. Its 16 inch Chrome Moly Vanadium steel barrel carries a black Melonite finish for corrosion resistance and a 1:7 twist rate that stabilizes a wide range of 5.56x45mm NATO bullet weights. A muzzle device is threaded onto the barrel at 1/2x28 and the direct impingement operating system cycles reliably from the included AR-15 magazine with a 10 plus 1 capacity. A Picatinny rail atop the receiver provides a continuous mounting surface for optics giving shooters flexibility to configure the rifle for their intended use. The 15 inch RPR free float handguard wraps the barrel in M-LOK slots keeping the shooter s support hand cool during extended strings of fire while leaving room to mount lights slings or grips exactly where needed. A black synthetic stock pairs with a B5 Systems Type 23 pistol grip to deliver a firm ergonomic hold that holds up under recoil. The rifle ships with a Mil Spec trigger and a selector switch safety and at 6.7 pounds and 33 inches overall it balances well for both range use and field carry. Configured for right handed shooters the Radical Firearms RPR is a CA compliant rifle ready for sale at GrabAGun.
