Radical Firearms FP85300HBAR7RPRBMSB 300 Blackout 8.5" Pistol

The Radical Firearms FP85300HBAR7RPRBMSB 300 Blackout 8.5" Pistol delivers compact firepower for operators who prioritize maneuverability without sacrificing terminal performance. Chambered in .300 Blackout—a round engineered for subsonic suppressed fire and close-quarters engagement—this 8.5-inch pistol bridges the gap between full-size rifle capability and handgun portability. Purpose-built for tactical applications, home defense, and specialized law enforcement roles, this platform serves professionals and civilian operators who demand reliability in confined spaces or vehicle-based scenarios.

The 8.5-inch barrel length optimizes the .300 Blackout cartridge's velocity window, ensuring consistent expansion and energy retention at intermediate distances while minimizing blast signature—particularly advantageous when running subsonic ammunition with suppressors. The flat-top Picatinny rail system provides unlimited optics mounting flexibility, allowing shooters to configure the pistol for red-dot sights, magnified optics, or night vision compatibility. Radical Firearms' commitment to precision manufacturing ensures tight tolerances and consistent accuracy, critical factors when operating in low-light or high-stress environments where every round counts.

This platform excels for operators running dedicated .300 Blackout duty systems, vehicle operators requiring compact firepower, and shooters building suppressed precision rigs. Law enforcement breaching teams and military support personnel appreciate the balanced ergonomics and rapid-follow-up shot capability. The modular design accepts standard AR-platform components, enabling straightforward maintenance and aftermarket customization for stocks, grips, handguards, and muzzle devices. Serialized as a registered firearm under federal law, this pistol requires FFL transfer and compliance with all applicable state and local regulations.
