  1. 5 out of 5

    I have experimented with several different muzzle breaks for several rifles in my arsenal, but the gen 2 cowl induction is hands down the best. I have it mounted on my M14 EBR and the recoil dropped dramatically. Furthermore, the customer service and staff are unbeatable. After ordering this muzzle brake it took 4 days and it was on my doorstep.
