The SRD556-QD is an Inconel 718 suppressor using fast-attach muzzle devices to mount the suppressor to the rifle. Inconel 718, a nickel alloy stainless steel, provides the highest level of durability, particularly with short-barreled hosts using supersonic ammunition. This 5.56mm suppressor comes with a muzzle brake threaded in 1/2"x28tpi to match the vast majority of modern rifles in .223/5.56 on the market today. The rear mount has wrench flats to torque the suppressor to the muzzle device.
While compatible with all traditional 90-degree shouldered barrels, when using SIG SAUER tapered shouldered barrels, the Taper Lok optimizes alignment, improving accuracy and greatly reducing point-of-impact (POI) shift. Wrench Flats provide easy removal, even with heavy carbon build-up. The wrench will automatically disengage the secondary retention latch with no ratchet teeth to wear out.
There is a secondary retention latch that is depressed to remove the suppressor from the fast-attach mount. Accessory muzzle devices and other thread pitches are available.
