According to their print # they sent me, It is supposed to have a parallel free bore. This has a straight free bore. The neck is really long and the neck is wayyy over sized from what it should be.

If you read, I never said that the chamber on this barrel was not straight. I asked if the McGowan chambers are straight. I know that their quality seems to go up and down all the time and it seems to be the luck of the draw when you order one. I had a 223 that the barrel looked like it was a factory Remington being that it had chatter marks in the last 1" of the barrel. I sent it back and they cut off the bad section for me and re crowned it. It shot great.

If someone here has ever made a cast of their chamber, I would like to know. It would speak volumes on how close they are.
