+1 what Scrat and Dragline said, the M1A in standard 22" configuration should do nicely for your purposes. The biggest hurdle is scoping it, you will need a mount and a cheek riser which can be found here http://www.desertwarriorproducts.com...pe_Mounts.html

Unless you get the sage stock like Scrat said, then you've got all the scope mounting RAILestate you need.
