Hi, I have a Tikka .308 and considering about muzzle brake. Can anyone tell me which type of muzzle brake is better if not the same. I was looking into a muzzle brake that would be drilled onto the barrel so that it's permanent and nothing is added on rather than being installed in such as screwed onto the barrel. Is there a difference in these two types of brakes? if so, which is better or worse or same?
