Key Features

Barrel and Ballistics

The 8.5-inch 4140 chrome moly vanadium barrel with Melonite finish resists wear and corrosion while delivering consistent accuracy. A 1:8 twist rate stabilizes a broad range of supersonic and subsonic .300 Blackout loads, making this pistol versatile for both suppressed and unsuppressed use. The 5/8×24 threaded muzzle with A2 flash hider allows easy attachment of muzzle devices and suppressors for signature reduction.

Gas System and Cycling

A pistol-length gas system and .750 low-profile gas block help ensure reliable cycling with subsonic ammunition—critical for suppressed operations. The HBAR profile provides rigidity that improves repeatable point of aim in follow-up shots.

Platform Durability and Ergonomics

Forged 7075-T6 upper and lower receivers with Type III anodizing give the platform strength often reserved for higher-end rifles. Standard MIL-SPEC components—forward assist, dust cover, safety selector, fire control group, charging handle and buffer system—ensure maintainability and parts commonality. The free-float thin rail supports optics, lights, and grips without adding excessive weight.

The MFT pistol brace produces a stable shooting interface and the pistol ships compatible with standard AR-15 magazines, including the included 30-round magazine. For a tactical shooter prioritizing compact control and modularity, the RADICAL FIREARMS HBAR checks critical boxes. View product details and pricing
