hello mate, i have a simmons white tail classic, 1.5-5x20. these scopes are superb, crystal clear. mine only has a max magnification of 5x. which is perfect during day light. no good at night its to small. the mag matey is the 3.5-10 part, your maximum mag will be x10. which is more than enough for airgunning. either of them 3 will be fine, i would get the cheaper of the 3, the smaller one because they are such good scopes that there wont be much need for the bigger scopes. hope this helps mate. mick
