Radical Firearms FP105300HBAR10RPRBTR BTR 300 10.5" AR Pistol

The Radical Firearms FP105300HBAR10RPRBTR BTR 300 Blackout 10.5" AR Pistol is a compact, high-velocity platform designed for operators requiring firepower in confined spaces without the legal complexity of a short-barreled rifle. Built on the proven direct-impingement AR-15 architecture, this 300 Blackout pistol excels in vehicle operations, CQB scenarios, and home defense where maneuverability trumps extended range. The 10.5" barrel length delivers subsonic and supersonic 300 Blackout rounds with optimal velocity and accuracy, making it equally effective with or without a suppressor—a critical advantage for tactical professionals and civilian defenders alike.

This AR pistol features a heavy barrel (HBAR) profile, which increases mass and thermal stability during sustained fire, reducing point-of-aim shift and improving shot grouping—essential when precision matters in high-stress encounters. The 300 Blackout cartridge provides superior ballistics in short barrels compared to 5.56 NATO, retaining energy and lethality at intermediate distances while managing recoil impulse through the rifle's direct-impingement gas system. At 7.15 lbs, the platform balances controllability with enough weight to manage recoil and maintain accuracy, while the compact 34.5" overall length ensures rapid target acquisition and shouldering in dynamic environments. The BTR designation indicates a refined receiver set engineered for tight tolerances and consistent performance across thousands of rounds.

Law enforcement tactical teams, private security operators, and civilian preparedness-minded shooters benefit from this platform's versatility and AR-15 compatibility with standard furniture and ancillary equipment. The 300 Blackout chambering pairs seamlessly with common suppressors and night-vision systems, enabling silent operations without sacrificing terminal ballistics. Users should note that this is registered as a firearm requiring FFL transfer; compliance with all federal, state, and local regulations regarding pistol possession and braced platforms is the responsibility of the buyer. The Radical Firearms BTR 300 delivers serious capability in a package that fits under body armor and through doorways—a genuine force multiplier for professionals and prepared citizens.
