I've been wanting to do a USGI Springfield Armory build. Since I'm doing a Springfield I figured I might as well use one of my SAI M1A's to donate the receiver since it says Springfield on it. Would it be a dumb idea to take off a perfectly good USGI barrel to install a perfectly good USGI SA barrel? One of my M1A's has a H&R barrel and the other a Winchester. They both shoot great. I explored the idea of buying an SAI receiver. The problem is too many mixed reviews on current production receivers for my taste. Both rifles I have are from the Valley Odrnance days. I intend to then use whatever barrel I take off for a build down the road on a nice forged receiver. Advice is appreciated. If I'm a dumbass tell me so. Won't hurt my feelings.
