thanks guys, but no one has really answered my original question. My break is permanantly attached, the gentleman I bought it from said it was factory installed. I know what the holes are for, dissipating energy, sound, etc. BUT my question is, since this is permanantly attached, and needs to be there to keep the barrel longer than the 16" minimum could a gunsmith fill in these holes thereby doing away with all of the "advantages" of the break. I need to keep the length but want to get rid of the noise and concussion. Simply cutting it off and recrowning is not an option. In theory my idea would basically just make a solid large end to the barrel.
