SOF OPERATOR 5.56 HUB 5.56MM

The SOF Operator 556 is a hard-use rifle suppressor engineered for modern 5.56 NATO carbines and assault rifles that demand uncompromising durability, reliability, and performance. Constructed from aerospace-grade IN718 Inconel using advanced 3D metallurgical additive manufacturing, the 556 is purpose-built to withstand the extreme heat, pressure, and abuse generated by sustained full-auto firing schedules.

Compact and maneuverable, the SOF Operator 556 measures just 5.30 inches in overall length while weighing 15.4 ounces, making it an outstanding choice for duty rifles, SBRs, patrol carbines, and tactical platforms where maintaining a compact profile is critical. Its advanced suppressor design helps reduce muzzle blast, flash signature, and felt recoil while preserving the handling characteristics of the host firearm.

Built around the industry-standard HUB 1.375x24 mounting interface, the SOF Operator 556 is compatible with a wide variety of HUB-compatible quick-detach and direct-thread mounting systems, providing exceptional flexibility for custom rifle builds. The durable NANO G protective coating enhances corrosion resistance and protects the suppressor from harsh environmental conditions and prolonged firing schedules.

Rated for unrestricted barrel lengths and full-automatic fire, the SOF Operator 556 is engineered to meet the demanding durability standards of the SOCOM Suppressed Upper Receiver Group (SURG) program. With a maximum velocity rating of 3,300 FPS, a recommended 3,000-round cleaning interval, and a limited lifetime warranty against manufacturing defects, the 556 delivers professional-grade suppressor performance for shooters who demand absolute reliability.
