Guntec USA AR15 Claw Multi-Prong Flash Hider Anodized Clear. The "Claw" muzzle device effectively works in conjunction with a "T" attachment to provide multi-prong device. The "T" attachment effectively accomodates a "D" ring while preventing the accidental deployment of the flash hider which happens most commonly when the muzzle is at a downward angle. Guntec USA multi-prong guards are the natural choice as no snag point is necessary. Externally the "Claw" muzzle devices are a straight-forward 2-piece design and install by unscrewing the "T" ring and "T" ring then tightening the "T" ring to the "T" ring. For reliable holding power and heat absorption the "T" ring is twisted and locked in place by hand.
