The rifle is a 5 digit S.A. Inc with all USGI parts except for the flash suppressor and bolt catch he claims he’s had it for 20 yrs
Makes more sense to know he took it to a blacksmith in a butcher shop rather than a gunsmith. Re-inventing the wheel is not a good idea in this application.

I'm buying the theory that the scallop was put there to engage the bolt catch since the complaint involved failure to lock back. Rather crude fix, but since the metal was removed from the front of the lug, it likely will stay together. Shooters choice..... Good Shooting. ...

Somebody has for certain ground on that bolt and ruined it.

Not much just asked me if I could fix it and I told him I would find a new bolt and get it head spaced and replace the bolt catch

After having my M1A out recently, then having looked at the picture of the bolt, I wonder if the gunsmith bumped the butt of the rifle on the ground, either by accident, or on purpose, then had the bolt lock drop, then release the bolt, as they will do. I could see that this might be why he ground that bolt like that, some stupid way to try to stop the bolt lock from dropping and releasing the bolt in those conditions.

I replaced the bolt with a TRW bolt that luckily headspaced perfectly. The bolt catch was riding high because of a ridge in the receiver above the cutout. This was pushing the bolt catch outward so it was lifting up on the inside portion which in turn made it hit the bolt. I filed down the ridge and now everything is sitting where it should be. I smoothed out the trigger, shimmed the gas cylinder, polished up the piston and did a basic once over on all the other parts to check for serviceability. Need to get it to the range and see how it shoots now.

in the importance of correctly identifying the source/cause of any apparent problem BEFORE taking corrective measures involving altering otherwise correct parts.
