I have an Automag TAC-1 with a older Whisper carbon fiber barrel and it is stuck. I have had this set-up for years and never had a problem because I was careful not to screw the barrel in too tight. I lent my gun and barrel to someone and it got screwed in too hard.
How do I get it undone? I sprayed it with WD-40 and then heated the body to loosen things up, but the carbon fiber part of the barrel started to separate from the aluminum threads.
Has anyone solved this problem before?
