The SRD556-QD is an Inconel 718 silencer using fast-attach muzzle devices to mount the silencer to the rifle. Inconel 718, a Nickel Alloy Stainless Steel, provides the highest level of durability, particularly with short-barreled hosts using supersonic ammunition.



The 5.56mm fast-attach muzzle device system is available in 1/2"x 28tpi threads matching the vast majority of modern sporting rifles in .223/5.56mm on the market today. The rear mount has wrench flats to torque the silencer to the barrel. There is a secondary retention latch that is depressed to remove the silencer from the fast-attach mount. The SRD556-QD comes with one 1/2"x 28tpi Taper-Lok™ muzzle brake.
