Warne medium qd rings - Warne Medium Quick Detach Rings w/Matte Finish 201LM

The QD feature in nice and works well. Fit the scope perfectly. The vertical mount was a bit tricky compared to horizontal mounts. Was very quick to zero in. Biggest complaint was that one of the screws was extremely difficult to remove, I thought I was going to break the head off the screw, or I was going to break the supplied provided getting it out. It was like this right out of the packaging. Once I did get it removed, I could see nothing wrong with the treads on the screw, but it went back in very tight, and I was fearful of cross threading. After a few times in and out it functioned normally, there must have been shavings or debris on the female side of the threads. Seems for the price that should not happen.
