Made to fit AR-15 platform applications, the Claw multi-prong flash hiders redirect expelled gases to obscure the flash and reduce muzzle blast and IR signature. The Claw muzzle device works with a T attachment to provide a multi-prong design. The T attachment accommodates a D ring and helps prevent accidental deployment when the muzzle is downward. The Claw is a 2-piece design and installs by unscrewing the T ring and then tightening it in place by hand.
