This may seem rather a basic question, but since the margin for error is pretty steep I thought it should not go unasked.
Choosing to mark a home made AKM pattern rifle, is the following acceptable/defensible?
(where ZYX = initials)
More specifically asked: Do I have to add "model", "caliber", "serial no." etc.?
Common sense would dictate that it can be inferred by the markings, but is required to be spelled out?
