Sig Sauer NG556-QD 5.56 NATO Rifle Suppressor Black 7.4" 19.4 oz NG556-QD

Sig Sauer NG556-QD

The Sig Sauer NG556-QD is a 5.56 NATO quick detach rifle suppressor built from Inconel and finished in high temperature black Cerakote. It measures 7.4 inches long, 1.67 inches in diameter, and 19.4 ounces. The LO-TOX design is intended to cut toxic fume exposure at the ejection port during extended fire. A QD mount and muzzle brake are included for fast install and removal.

Monolithic core construction gives the suppressor the strength needed for hard use and heat. The Clutch-Lok system uses an intuitive tactile locking ring with infinite radial locking positions for a secure, repeatable mount. A flash reducing end cap lowers the visual signature in low light and tactical settings. High temperature Cerakote helps the Inconel body resist wear while staying serviceable in harsh conditions.

This suppressor fits 5.56 NATO rifles that need a full size QD can for duty, training, and modern carbine work. The included muzzle brake and mount keep the package ready to attach without extra hardware. Shooters who want a black NG series 5.56 suppressor with Clutch-Lok mounting, flash reduction, and reduced gas blowback will find the NG556-QD built for long sessions and field use. NFA rules apply.
