Things I liked:I put this scope on my NPSS with the leapers medium height mounts. I had to use some shims so that the lens covers would go on the scope. The 44 mm objective is large. The first scope had a loose adjustable objective side wheel so I called PA and they sent me a return postage label. I got the new scope back very quickly, installed the 80 mm side wheel and sighted it in. This scope rocks. It is very clear, solid, (doesn’t move when shot), the side wheel objective adjustment is a plus, and the elevation and windage adjustment turrets have locks built on them so you don’t need to carry tools. I am glad I purchased this from PA. Their customer service is top notch. Things I would have changed:This scope has such a wide range of applications that it would be nice if it was offered with or without rings. It comes with weaver mounts and I needed 9mm so now I have extra rings that I had to pay for and cannot use (at least now). What others should know:This is a great scope for the money. You might need a magnifying glass to read the range estimation chart that is included with the scope.
