The 3 to 9 by 40AO is one of our most popular scopes. With AO (adjustable objective) you are able to adjust the scope for maximum target clarity. With this scope you are able to adjust from 10 yards out to infinity, which makes it ideal for airguns, all the rimfire series cartridges and it would still happily be at home on a triple two 223 and in some cases if you want larger calibers. The scope has a 1inch main tube, is matt finished to stop any glare and is equipped with quarter click adjustments which should be fine enough for any body’s shooting. The scopes are shock and recoil proof, have fully coated lenses and they are fog and water proof. The scope is also supplied with a good set of lens covers. The price on these scopes is also very good and with our excellent Gun City warranty you should have no trouble with these.
