Finish on bolt carrier assembley

LRRPF52, Thank you for your reply. I have sent Mark at PF an email asking if they coat the barrel extensions that they use on their builds. That seems to be the only way to get a coated barrel extension, possibly. Certainly the barrels directly from Lilja are not coated? You answered exactly what I wanted to know and I really appreciate your sharing your knowledge and experience with us (me). John
