The Radical Firearms FP10.5-5.56M4-10RPR is a semi-automatic AR pistol chambered in 5.56 NATO, built on the mil-spec RF-15 platform with MIL-STD upper and lower receivers. Designed as a compact, lightweight firearm, it features a 10.5" M4-profile barrel with a 1:7 twist rate and a 1/2x28 thread pitch, paired with a pistol-length gas system for reliable cycling.

The handguard is Radical Firearms' 10" RPR (Radical Precision Rail) free-float system, which provides a mounting platform around the barrel for optics and accessories. The black anodized finish gives the pistol a durable, no-frills build suited to a variety of roles.

This AR pistol ships with one 10-round magazine, a magazine lock, and a rear takedown pin. The FP10.5-5.56M4-10RPR delivers the 5.56 NATO AR-15 platform in a short, agile package.
