The Sig Sauer SLXMG (brand part no. NG68SPEAR-QD) is a 6.8x51mm suppressor finished in Coyote, built to the same specification as suppressors fielded by the US Department of Defense. Sig Sauer uses a LO-TOX design to minimize toxic fume exposure from the ejection port, monolithic core construction for machine-gun-rated strength and durability, and a Clutch-Lok quick-detach mounting system for consistent, reliable attachment. The SLXMG favors shooters running 6.8x51mm platforms who want a mil-spec-pedigree suppressor.
