So before you all flame me for beating on my gun with a socket and hammer I relize that I am a dumb a$$. I tried to ues the socket method to remove the dimples. I failed because I used a socket that was the correct diamater but then tapered up to a larger diamiter. Now the tube is slightly flared and does not accept the extention tube. I know that it is close because the barrel will go back on with a little effort. I know somone has done this how did you fix it?
