Hi
I have a Mk2 meteor with a slack breech that no matter what I do it keeps on eventually working loose. Has anyone ever changed the Breech pin for something like this (see image link below)with any success. I thought of countersinking both sides of the air chamber to accept the bolt and nut, rounding off the nut for an interference fit into the chamber. Then locking in place with threadlock
