Sig Sauer .223/5.56 Caliber Suppressor with Quick Detach Mount

Nickel Alloy Stainless Steel.
Sig Sauer 5.56mm Suppressor.

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.

Easy Removal Wrench Flats.
Taper Lok Optimized Alignment.

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.

Secondary Retention Latch Supressor Removal.

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.
