This is the best quick-lock Peltor/liberator mount for mich/fast helmets. Don’t cheap out on another mount, get this one and get it right the first time.The product was damaged before I even replaced my old set. With one of the mounts for the tabs was already broken I replace the old ones with new and just used my old one in place of the new broken one.Not the most secure. Both sides needed to be bent into shape so they would securely cover my ears with pressure. But, even when I did that, it still did not reduce enough sound from live fire. I end up using foam muff under the comms.The product seems like it would work until you actually set them up and attach peltors. These do not allow the ear muffs on your comms to press against your ear and sit nearly a half inch away from your face.
