Not sure what type rifle you are putting it on, if it is an AR flat-top then a scope change is easy and quick. Otherwise I would opt for a 2-7 I have used a 2-7 Burris on an AR and it was quick and easy, not as quick as my 1.5-4.5 but much better for distance. Any good 2-7 or 3-9 should work just fine, even a good 4-12 would worry me at all, keep it turned to the low end and adjust magnification up as you need it. The higher magnification scopes when not used from a bench or at least a bipod appear to have a lot of movement at higher magnification but that may be my inner wobble.
