Why would you demil a Garand????
(Seriously) there a probably legal issues, as to where him could bring it.
I bought several de-milled for a Civil Air Patrol color guard unit.
It allows easy access to government buildings and large events with the drill out and de-milled stamp.
Plus, it removes any serious concern of someone doing something stupid. (ie: someone bringing a live round from home and showing their friends how it chambers.....)
