Radical 300blk 8.5" Rpr Hg 30rd Blk

The Radical Firearms 300 Blackout 8.5" Rifle Platform Hbar 30rd Black is a semi-automatic AR pistol engineered for subsonic and supersonic 300 Blackout performance in a compact, maneuverable form factor. With an 8.5-inch heavy barrel, this platform delivers the ballistic advantage of 300 Blackout—a cartridge designed specifically for short-barrel velocity retention and suppressor compatibility—while maintaining the modularity and ergonomics operators expect from AR-pattern platforms.

The threaded heavy barrel accepts standard muzzle devices and suppressors, critical for 300 Blackout systems where subsonic loads demand sound signature management. Pistol-length gas system tuning is optimized for the shorter barrel to ensure reliable cycling across both subsonic and supersonic ammunition. The 7-inch M-Lok handguard provides tactical mounting flexibility for optics, lights, and other accessories, while the MFT Engage V2 grip delivers ergonomic control and modularity. Anodized black finish resists corrosion during field use. The A2 flash hider reduces muzzle signature and includes one 30-round magazine.

This 300 Blackout AR pistol configuration serves operators, precision shooters, and tactical trainers seeking suppressed capability or compact defensive accuracy in confined environments. The combination of cartridge ballistics, barrel length, and gas system makes this platform particularly effective for close-quarters scenarios, home-defense setups, and dedicated short-range training. Weighing 6.63 pounds, it balances controllability with enough mass for stable handling. The 300 Blackout cartridge itself offers superior barrier penetration and terminal performance compared to intermediate rifle rounds when matched to appropriate ammunition selection.

The 300 Blackout platform has become the industry standard for suppressed AR builds over the past decade, offering shooters a genuine advantage in hearing preservation and muzzle signature reduction while maintaining stopping power. Radical Firearms produces AR-pattern firearms with an emphasis on component quality and consistent performance, making this 8.5-inch platform a reliable choice for buyers seeking verified specifications and proven reliability in a compact package.
