holes drilled in the area for a rear target sight on a 1903. Mauser, ect, wont weaken it enough to be a safety issue.
you may, have an issue with a case head failure if the bolt sets back the safety lug into that part of the receiver, that being said, if that happens to 6-48 holes wont make much diffferance..
and any one who drills extra holes in a 1903A4 shoot be kicked in the biskets.
Thanks for the reply.
I believe the the gun plumber who built this rifle assumed room temp some time ago.
The damage is done. Long as its safe, may as well punch some paper with it.
