I've got 2 of them (though mine are mil-radian). Great scope and features for the $. In fact my Frontier & Sidewinder both outperformed (clarity & FOV) a few others similarly priced scopes.
I have a mil dot 4-16x50 Sidewinder and I really like it. Its riding on a spring piston rifle and has performed awesome. I also recently got a Hawke Airmax 6-24x50 that I like just as well. Both are clear, forgiving eye relief and snappy focus. I do find the illuminated reticle useful for dark targets without being too much. And the reticles are not too thin nor too thick.
Two thumbs up on Hawke optics. Bought my first one for a AirArms S400. Since then I've bought 4 more and no problems with any of them. Great value for the price.
