I'm pretty sure this is the right place to put this, so here it goes. I was just looking through my latest issue of Shotgun News and I saw an ad for "non-firing" military surplus M1903 springfield rifles. The ad said that they have been modified to prevent firing. I was just wondering how they modified them, and if its even legal, how hard it would be to get them back into firing condition? Come to think of it, maybe this aught to go in the gunsmithing forum?
