Radical Firearms 300blk 10.5" 30-Round Threaded Barrel AR Pistol

The Radical Firearms 300blk 10.5" 30-Round Threaded Barrel AR Pistol is a purpose-built platform engineered for close-quarters engagement, home defense, and tactical operations where a compact rifle system offers superior control over traditional handguns. Chambered in 300 Blackout—a cartridge specifically developed for suppressed subsonic performance and barrier-blind terminal ballistics—this AR pistol delivers the ergonomic familiarity and modularity of the AR platform in a form factor that bridges the gap between duty pistol and short-barreled rifle. The 10.5-inch barrel length optimizes velocity and muzzle velocity consistency for 300 Blackout's design parameters while maintaining genuine portability in confined spaces, vehicles, and tactical entries.

Built on proven AR architecture, this Radical Firearms pistol features a threaded barrel compatible with industry-standard suppressors, sound moderators, and muzzle devices, allowing operators to customize acoustics and recoil management to mission requirements. The 1/2x28 thread pitch is the universal standard for 300 Blackout applications, ensuring seamless integration with any threaded 300 Blackout suppressor or flash hider. Weighing 6.94 pounds, the platform remains manageable in dynamic tactical scenarios while the 30-round magazine capacity aligns with modern law enforcement and defensive load-out standards. The AR pistol configuration—featuring a pistol brace compatible design—provides the accuracy and sight radius advantages of a rifle stock geometry without the NFA registration requirements of a traditional short-barreled rifle when configured appropriately.

Law enforcement tactical teams, military special operations units, and serious defensive shooters benefit most from this platform's suppression-ready design and subsonic-optimized cartridge pairing. The 300 Blackout cartridge delivers superior penetration through intermediate barriers—a critical advantage in real-world threat scenarios—while suppressed subsonic loads maintain subsonic velocity for hearing-safe operation without sacrificing terminal performance. Compatibility with standard AR lower receivers and upper assemblies ensures parts commonality with existing arsenals, reducing logistics complexity and training overhead. The Radical Firearms 300blk 10.5" system represents professional-grade hardware for operators requiring precision, reliability, and mission flexibility in a compact platform.
