Radical Firearms BTR 300 Blackout 10.5" HBAR Pistol FP105300HBAR10RPRBTR

The Radical Firearms BTR 300 Blackout delivers suppressed and unsuppressed versatility in a compact 10.5-inch platform. This pistol-length firearm bridges the gap between close-quarters maneuverability and effective downrange performance, offering shooters a reliable platform for both subsonic and supersonic ammunition.

What Makes This Different

The BTR (Battle Tested Ready) series incorporates mil-spec components with enhanced manufacturing tolerances typically found in higher-priced rifles. The heavy barrel profile (HBAR) provides superior heat dissipation compared to standard pencil barrels, maintaining accuracy during extended shooting sessions. Radical Firearms machines each upper receiver from 7075-T6 aluminum forgings rather than using cast components, resulting in tighter dimensional consistency.

Key Features

• 10.5-inch heavy barrel profile optimized for 300 Blackout ballistics
• 7075-T6 aluminum upper and lower receiver set with Type III hard coat anodizing
• M4 feed ramps and chrome-lined barrel extension for reliable feeding
• Standard AR-15 magazine compatibility accepts all STANAG pattern magazines
• Picatinny rail system allows mounting of optics, lights, and accessories
• Carbine-length gas system with low-profile gas block
• Standard mil-spec trigger group and bolt carrier group included

The 300 Blackout cartridge performs exceptionally well from shorter barrels, losing minimal velocity compared to longer configurations. This platform excels in home defense scenarios where maneuverability matters, while maintaining effectiveness for hunting applications within appropriate ranges. The heavy barrel profile reduces point-of-impact shift as the barrel heats, maintaining consistent accuracy through multiple magazine strings.
