Radical Firearms BTR 300 Blackout 8.50 inch Heavy Barrel MLOK Pistol 30 round Polymer

The Radical Firearms FP85300HBAR7RPRBTR BTR 300 Blackout AR pistol brings the BTR series into a compact, hard-hitting platform with an 8.50" heavy barrel and 10" RPR free-float M-LOK rail that delivers improved accuracy, consistent harmonics, and plenty of room for lights, lasers, or backup optics while keeping your hands cool during extended strings of fire. Built on MIL-STD upper and lower receivers and finished in black polymer for lightweight durability, this semi-auto pistol in 300 AAC Blackout (7.62x35mm) offers a 30+1 capacity and is ideal for suppressed shooting, close-quarters defense, short-range hunting of medium pests, and carbine-style training where compact maneuverability matters. With no fixed sights, the platform is intended for users who prefer red dots or low-profile optics, and the HBAR profile barrel preserves velocity for heavier bullets while remaining compact. As a firearm, this model requires FFL transfer and follows all regulated transfer procedures; its ergonomic black polymer grip and overall balance make it comfortable for rapid target transitions and range sessions. If you're searching for a compact 300 Blackout AR pistol with an M-LOK free-float rail, heavy-barrel performance, and a rugged MIL-STD build, the Radical Firearms BTR 8.50" delivers a focused, ready-to-configure package.
