Boogered up threads - Faxon Firearms EXOS-533 Pistol Compensator

Very nice comp. Hard did not want to thread on though. I looked at the threads before I tried and they looked like they had some gunk, residue, or shavings in them. Allot of turn on, back off, clean threads. Eventually got them cleaned out. Still really hard to thread on and off, but doable. Not the best quality that I expected from faxon. Will probably go with another brand on my 19mos.
