I bought this for a new rifle since I was getting binding on the tube using a dovetail style mount. This DNZ mount fit perfect, no binding on the tube. Much easier to install than the double dovetail set-up and stronger since it is machined out of one solid piece of stock. The price is very good when compared to buying a base and rings separate. I am considering replacing my other one piece scope bases with the DNZ mount.
Pros: Absolute perfect fit. The scope aligns "dead on" and slides easily when adjusting for the eye relief, there is no binding on the scope tube at all.
Cons: none
