OK guys I'm thinking that some of you guys have already done this, but due to a twist I now have to. I've got this FAL that has been in my gun pen for a while and I need to rebarrel it. I've looked up every bit of info I need to do this project. Except that I know there are some steel rods to gauge the locking shoulder, and I lost my notes:slap: on where to source them and the best price and selection for the shoulders. Any help would be appreciated.Thanks guys.
