The SureFire Mini with maximum sound attenuation Employs SureFire Total Signature ReductionA(R) technology to virtually eliminate first-round flash, and reduce sound and dust signatures Optimized for 14.5-inch and longer barrels on 5.56 mm M4 variants Unprecedented performance for its size Make Every Inch Count. When the going gets tight, an inch can mean the difference between efficiently engaging the enemy or getting caught in a vulnerable position. That's why we created the SOCOM556-MINI2. It delivers performance levels similar to the model that assured SureFire's victory in the demanding USSOCOM suppressor trials, but in a more compact package optimized for 14.5-inch and longer barrels. A mere 5 inches long, it places a premium on efficiency and maintains the quality synonymous with every SureFire suppressor. Our innovative internal baffling significantly decreases back pressure, cyclic rate and gas blowback. The net result is a tremendous reduction in sound and dust signature with virtually undetectable first-round flash and minimal, consistent point-of-impact shift.
