Their design not only passed SOCOM's rigorous trials, it obliterated the competition in every aspect of performance and durability. What better way to earn the right to wear the esteemed SOCOM name. Designed specifically for use with 5.56 mm (.223 caliber) weapon systems featuring a minimum barrel length of 10 inches, the SureFire SOCOM556-RC2 showcases SureFire's know-how in cutting-edge suppressor design and incorporates the latest in manufacturing techniques and materials to produce the finest tool of its kind.
