SIG SAUER’s SURG556 is a mission-proven, high-flow 5.56 mm suppressor engineered to exceed contract requirements for accuracy, durability, reliability, signature reduction, thermal limits, and low toxicity. Its Forward-Flux multi-flow core dramatically reduces gas blowback and fouling to keep your sight picture clear and your rifle cleaner under sustained fire. A detachable titanium hexagonal heat shield lowers thermal signature, improves handling, and helps prevent incidental burns during dynamic movement or rapid transport. Built around a monolithic Inconel steel core and featuring an integrated flash hider, the SURG556 is full-auto rated and purpose-built to thrive in the harshest conditions.
