The Radical Firearms RF FP10.5-556M4-10RPR-BMPSB is an AR-style pistol built on MIL-STD upper and lower receivers with a 10.50-inch M4-profile barrel and a free-float RPR rail for accessory mounting and improved ergonomics. It is chambered for .223 REM/5.56 NATO and ships with a single 30-round magazine. For a practical optic under $1000 that suits the platform, consider a low-power variable such as a 1-6x (for example, the Vortex Strike Eagle 1-6×24) to cover close-to-mid-range engagements without adding excessive weight.
Common applications for this pistol include precision-focused range training and action/competition stages where compact AR platforms are permitted and advantageous.
