The real question is, what are you going to do with it? Are you going to sit at a bench on the range and punch holes in paper and be happy with little group? Are you going to run through the woods with a buddy for a coupel of miles while stopping to shoot, chop wood, carry a log and shoot out of the back of a moving pick up truck and then move six cinder blocks around?

A non magnified dot sight or holo sight can make hits out to 250m all day. If you want to print little groups on paper, get something with magnification.
