Radical Firearms FP10.5 5.56 NATO 10.5" M4 AR Pistol w/ Breek Arms Mini Brace

The Radical Firearms FP10.5 is a compact AR pistol chambered in 5.56x45mm NATO, built around a short 10.5" M4-profile barrel and configured for shooters who want a lightweight, maneuverable platform. This BMPSB-equipped variant ships with a Breek Arms Mini Pistol Stabilizing Brace mounted to the pistol buffer tube for one-handed or braced shooting.

The 10.5" M4-profile barrel is machined from 4140 chrome moly vanadium steel and finished with a Melonite (nitride) coating for corrosion and wear resistance. It features a 1:7 twist rate and a true 5.56 chamber with M4 feed ramps, allowing safe use of both 5.56 NATO and .223 Remington ammunition.

MIL-STD forged upper and lower receivers provide a durable foundation, and a 10" RPR (Radical Pistol Rail) free-float handguard shrouds the barrel for accessory mounting. The pistol operates on a standard AR-15-pattern semi-automatic action and accepts standard AR-15-pattern magazines for a 30-round capacity. The receiver and brace are finished in black throughout.

This is a new current-production Radical Firearms pistol, sold in its factory configuration.
