Do you have a M1 right now, or are hoping to get one. The M1 rifle loads from the top with a 8 round .30-06 enbloc clip and a scope would mount right where the clip is inserted, so to properly mount the scope it has to be mounted to the side. If you really want a scope mounted M1 type rifle order one of the M14S rifles that have just been imported by MARSTAR. About 1/2 the price of a M1 rifle, is .308/7.62 magazine fed from the bottom and a normal top center mounted scope mount is available.
