AAC 51T Muzzle Brake 1/2x28 – AR-15 / 5.56mm / .223

The AAC 51T Muzzle Brake serves as a quick-detach mounting system for 51T-compatible suppressors while providing effective recoil reduction when shooting unsuppressed. The 51T taper-mount system ensures repeatable, secure lockup with proper alignment for consistent point of impact. This brake works as a stand-alone muzzle device or as a suppressor host, giving shooters flexibility in configuration.

The 1/2x28 thread pitch is standard for AR-15 rifles chambered in 5.56mm and .223 Remington. Installation requires a crush washer (typically included) or shims for proper timing. Steel construction with a durable finish handles repeated suppressor mounting cycles. Note: This is a muzzle device only; suppressors require ATF Form 4 approval and NFA compliance.
