Knights Armament KAC 5.56mm AR15 QDC 3-prong flash hider / mount
this is the current production flash hider / quick disconnect mount for the KAC QDC Suppressor
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.
as this is a take-off from a new rifle, it does not come with shims. If you need shims, we offer those here.
Thread Size: 1/2"x28
