I was surprised when I opened the box, to find scope rings that had a rail system on 3 sides of the scope mount. The picture that I looked at, did not have these rings shown. I did need a set of rings that would mount to a picatinny base. I decided this was a minor "flaw" and mounted them up on my Remington 700. The CAA Rings were easy to install, are extremely secure, and I have had no loosening of the ring set after multiple rounds out of my .308.
The only reason I gave the "3" on the features, is due to Optics Planet having the wrong pic in the ad.
Pros: Sturdy, Easy to Install, Scope is not going to move.
Cons: The wrong picture in the ad
