1-4 the best you can afford, the leupold can really seem like you are looking down a little tube but still a good optic, burris makes a good one might be 1-6, if you really are in potentially dangerous situations then the NF is one. crystal clear glass, true 1x magnification, 30mm tube, great eye relief, illuminated reticle if needed, and large field of view. if its simply for bambi's then lesser than NF is not a sacrifice.
