I hope to put a quality 2-7x variable from Burris, Leupold, T/C and the like on the 308 I get for my Encore. I've used Nikon and B & L 2x scopes and liked them on Contenders for up to 100M. The greater magnification of the 2-7x variable will help for accurate bullet placement at the longer effective range the 308 gives you. Others have said don't scimp and get the low end stuff because you'll regret it sooner or later: I agree with that philosophy. Quality has a way of speaking for itself.
