The Sons of Liberty Gun Works NOX9 is a compact, high-performance 9-port muzzle device designed to balance flash reduction, control, and suppressor-mount compatibility in a durable, low-profile package. The black finish and precision-machined body give it a clean, purpose-built look, while the open-prong design and directional porting help manage muzzle movement during fast follow-up shots. This model is marked NOX9-SF, the SureFire-compatible version rather than the more common Dead Air KeyMount version.

The revolutionary SureFire WARCOMP-556-1/2-28 flash hider, which fits M4 / M16 weapons and variants with ½-28 muzzle threads, is the world’s most shootable flash hider. Its patent-pending design provides three valuable functions: It provides over 99% reduction in muzzle flash compared to a plain muzzle, which helps to conceal the shooter’s location and preserve his dark-adapted vision. It virtually eliminates muzzle rise, which enhances monitoring of target reaction and staying on target for faster follow-up shots.
