i've heard alot of bad things about the air max scopes, not very well made from what i hear, reticles shaking loose and all sorts. i personally wouldn't touch em with a barge pole
i've got a hawke night-eye 3-9x50 IR mildot reticle, its a nice scope, fairly cheap too, good for if ur doing any shooting where light may be scarce, or u just fancy showing off that your reticle glows red on 11 different settings
