The 5.56mm SIG-SD silencers feature a unique tapered shape that allows for use under certain longer handguard and rail assemblies. While most suppressors on the market have a 1.5″ diameter tube SIG SAUER opted for a full 2″ tube. This allows for greater gas volume in a compact package reducing heat back pressure and sound signature while remaining compatible with all rail-mounted SOPMOD accessories. A high nickel content stainless steel is used for both the tubes and the baffles. This significantly reduces material degradation and delivers a sustained full-auto capable silencer with longevity not currently found in competitive offerings.
