It should arrive with a work sheet with very vague description of what the gunsmith did. They don't go into a lot of detail. The phone call may or may not answer your questions as the person on the phone isn't a gunsmith.
Guess they want their repair guys repairing and not writing out detailed descriptions of what they did.
Main thing is it works as it should.

Cue sound of Head slap.
