Knight's Armament Co 5.56mm QDC 3-Prong Flash Eliminator Kit

The KAC 3-Prong Flash Eliminator is an extremely effective flash suppressor design that also serves as a platform for attaching a Knight's Armament Quick Disconnect Coupler (QDC) sound suppressor. This muzzle device was engineered to not only neutralize a rifle's flash signature, but also to eliminate the sympathetic ringing that is often associated with open prong flash hider designs. Comes complete with a 7-piece shim kit and installation instructions.
