I just purchased my first M1A. It is a supermatch. I was thinking of replacing the oversized stock with a synthetic. Also, is there anything wrong with an aluminum mount? I was looking at the new Millett M1A mount. I have a Spfld Gen 3 but not fond of it. I have a Leupold Mark 4 M3 to put on it. Was also looking at TPS rings. Any advise would be appreciated.
