Beware of picture, and description of this product - Leupold AR Mark 1 IMS Rail Mount

This rail mount is NOT like the one pictured. The one pictured is actually the Mark 2 base that has the hex screws that you loosen, and then the base can be removed from the top, sort of like a quick release would. The Mark 1 actually has torx screws that have to be completely removed, and then you have to slide this base on your flat top from the back. Look on Leupold's web site, and you can see the difference in the Mark 1, and Mark 2. I called O.P., and they said sometimes they use the same picture to describe two different models of a product. Not a very smart sales tactic, if you ask me. I just ordered the Mark 2, and will be returning this one. I'm still giving it 5 stars, because it is a very well made product, and O.P's. customer service is excellent. It's just not what I wanted for my particular set up.
