A drill gun is for display only. they do not function. DON'T WASTE YOUR TIME
I'm not sure I totally agree. But first, I've never seen a Sarco 1903 and therefore can't comment on their condition. BUT...
Its my understanding that most, if not all, 1903 rifles sold by the CMP recently (when they still had them) were returned from VFW and American Legion posts. They only fired blanks at funerals and Memorial day celebrations etc. How they were cared for, and/or abused, I don't know. I was fortunate to get a 1903 from the CMP last February. I assume that it was a former "drill gun" and it is a decent shooter.
