Sig Silencer SRD556-QD 5.56mm, Taper Lok W/ Fast Attach Muzzle Device, 1/2×28, Black
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.
