      Kac 556 suppressor

      Posted by Devan Foshee on 3rd Jun 2026

      As usual, kac really does make a great product, it sounds good, not the quietest but sounds good, not heavy, great flow through and great flash mitigation! Very happy with it and as everything I've bought from AU, super fast shipping at a good price! Recommend again!
