Sakofan summed it up exactly right. I owned one and will never own another. Great Idea but very poor quality in my opinion and experience. For what it's worth.

I wouldn't put one on a slingshot. Tried to zero one for a friend using a chamber laser wouldn't even zero. The closer you got to the end of max elevation the more it would pull the reticle horizontally. Ask shepherd to sell them to our enemies all of our troops will be safe for sure. Save your pennies don't DICK around buy a Nightforce and never look back.
I'll go with Sakofan on this one. Neat concept in theory, but really poor glass and over all quality. Not to mention they have a stiff price tag to remind you after you purchased it, what a huge mistake you made.
