Description

The Sig Sauer NG556C-QD is a compact SLX-series suppressor designed for use with .223 Rem / 5.56 NATO. It uses a monolithic Inconel core and the Clutch-Lok quick-detach mounting system to provide a low-profile, repeatable attachment solution. The SLX multi-flow internal design is intended to reduce flash and lower the amount of toxic gases routed back toward the shooter.
