The Daniel Defense Muzzle Climb Mitigator Gen II redirects propellant gasses through calibrated ports, countering both recoil and muzzle climb. Less recoil and muzzle climb results in quicker, more accurate follow-up shots and reduced fatigue. Machined from aerospace 17-4 stainless steel. Minimal chance of corrosion. Salt bath nitride finish keeps maintenance to a minimum. The Daniel Defense Muzzle Climb Mitigator Gen II comes in standard length and 1/2 x 28 TPI.
