Radical Firearms RPR 300 Blackout 16" Carbine

The Radical Firearms RPR 300 Blackout 16" Carbine is a purpose-built platform engineered for suppressed fire, close-quarters tactical operations, and subsonic ammunition performance. Chambered in 300 Blackout, this 16-inch carbine delivers the ballistic efficiency and terminal performance required in law enforcement, military, and professional defensive applications where conventional 5.56mm platforms fall short. The 300 Blackout round excels in urban environments, vehicle interdiction, and noise-sensitive operations where sound signature matters as much as lethality.

Built on the proven AR-15 platform, the Radical Firearms RPR 300 Blackout carbine features a 16-inch barrel optimized for subsonic and supersonic round compatibility, weighing a controllable 8 pounds fully assembled. The M4-style profile geometry reduces muzzle rise and accelerates target re-acquisition in dynamic shooting scenarios, while the 1/2x28 threaded muzzle accommodates suppressors, flash hiders, and muzzle brakes without modification. The free-floating barrel design minimizes harmonic distortion, critical for achieving the accuracy consistency demanded in precision rifle work and suppressed shooting applications where velocity variation directly impacts point-of-impact shift.

This carbine is ideal for shooters prioritizing quiet lethality—tactical operators, home defenders, and precision shooters running suppressors who require subsonic ballistic performance without the velocity penalties of larger host platforms. The 300 Blackout chambering integrates seamlessly with standard AR-15 lower receivers and magazine systems, allowing existing AR owners to convert or cross-train without platform learning curves. Competency with this system translates directly to CQB environments, breaching operations, and suppressed precision work where the 300 Blackout's moderate recoil signature and reduced sound signature provide decisive tactical advantage over conventional intermediate cartridges.
