Next-generation SureFire gas flow dynamics further reduce flash signature. Revised muzzle design provides greater durability when subjected to extreme abuse. 60% less back pressure results in less toxic gas in the operator's face, improved reliability, superior recoil control, and a cleaner firearm. 100% Inconel construction delivers the combat-proven reliability and durability that established SureFire's SOCOM suppressor legacy. Optimized for 6mm ARC, the MINI4's 5.8-inch length provides a lighter, more compact suppressor for minimal impact on handling characteristics. Backward compatible with millions of SureFire SOCOM Fast-Attach muzzle devices already in the field. Optimized for SF3P, FH556RC, and WARCOMP open-tine flash hiders. Proudly designed and manufactured in the U.S.A. SureFire SOCOM6-MINI4-BK SOCOM6-Mini4 6mm ARC 1.50" Black Inconel
