I would like the opinion of the board on this.
I have a L1A1 / Imbel unmarked metric receiver where I noted that the locking shoulder had moved slight out after a recent session.
I tapped it back in but the forced required was very low.
I removed the locking shoulder (marked "4") and the "shank" measured .2955 inches and the locking shoulder hole in the receiver measured .296 inches. A slip fit instead of an interference fit.
The end of the locking shoulder shank was crudely chamfered but the region that engages in the receiver appears to be untouched/finish intact.
With the exception of the chamfer, I find it hard to believe that the locking shoulder shank was undersized as it came from the factory. But.......
The question.
I understand that the standard locking shoulder shank should measure .2974 inches and the "1" shank is .2982 inches, should I go with a standard or the "1" oversized replacement locking shoulder to correct the issue?
Your guidance is appreciated.
Thanks,
Hoover
