pathfinder,
Even though you say it is in less than prime condition, spend a little time searching on the net for 03-A3's and see what they're asking for them. You know the on-line auctions, etc. There are allot of sites on line for collectors too. Go to Google and put in milsurps 03-A3 or something like that. I'll just bet you could get $400-500 for a good shooter that is original with same s/n and stocks! Heck...they get that much for sporters cut-down!
