Everyone looks for something different in scopes; I try to look for versatility. To me, scopes with AOâ€™s are better than scopes without them. Scopes without AOâ€™s are normally centerfire scopes with their parallax set at 100yds. Anymore I look for scopes that have an AO that can go down to 10yds or so & out to infinity. I also like scopes with a little more magnification than most people. And it doesnâ€™t bother me in the least to buy a scope thatâ€™s Springer airgun rated. Actually some of the better deals out there right now are the Simmonâ€™s whitetail classic or prairie hunter & the 44mag. Leapers just came out with their 5th generation scopes that are killer. Muller is also a good solid scope name with their APV line along with the target & eradicator line of scopes. I just like scopes that are capable of doing more than 1 type/style of shooting. Itâ€™s nice to have a scope that I can use on an airgun in the basement in the winter, put it on a 22 & target practice with it & then put it on a centerfire & hunt groundhogs out to 1000yds. The last hunting scope that I bought was actually a straight 6x. Itâ€™s a compact mildot scope with an AO that goes down to 5yds. Itâ€™s a leaperâ€™s 5th generation scope called a bug buster & they call it a bug buster for a reason. Itâ€™s made to take out bugs 30yds & in. But it can be used on any rifle from a Springer airgun up to & including the 338mag with an AO that goes from 5yds to infinity.
