Yea, I was a little hesitant to try only one ring. I saw a post last year, I think it was on this site, that showed a large red dot scope mounted on the rear open site area and it used only one ring. I thought I would borrow that idea and try this. The scope is very light and I have done a lot of testing with it. I made sure I went with the widest ring I could find. It has behaved really well. If I ever come across a longer, low Weaver base like a scout mount, I may give that a try and use two rings.
