I sent my M1A Bush rifle to Springfield Armory to have them look at it- it always shot quite high w/ sight bottomed. My gunsmith thought it might be the threds. I called SA & Randy said that they have to replace the reciever (guess the gunsmith was right) and that it would have to be a post-ban from now on. I found information on the ATFs FAQ page that said if the old frame is destroyed, a new reciever can be marked with the same serial number, or a "marking variance (27 CFR 178.92) can be obtained. Does anybody have any information about this they could share with me? It came with a folding stock, I want to be able to use it, & retain it's value. Thanks
