Still don't quite understand the problem.
The bull barrel slips over the Mauser barrel. The Mauser barrel should be cut at the end of the bull barrel. ( approx) so the three set screws can center and secure the bull barrel. Any fitting at the receiver should be already done as in the draw ing above.
The booster fits over the bull barrel and should not touch the Mauser barrel at all.
Can you post a pic?

Hi, sorry to hijack this thread but I have been trying to PM a reply to the PM you sent me Kpax and your inbox is full.

Also, thank you to Dave, Pat, and Carson for this awesome kit! I love how mine has turned out. This was my first prop build and I had a lot of fun working on it.
