I'll present this point about all the normal rings that are basically using the same engineering. They pinch the tube and compress it either down, or from the side, or at an angle like Spuhr. This can cause the parallax slider mechanism in the tube to bind up or be constricted which ill affects the function of different things in the scope. I've read about it over and over for the last 14 years.
It's true that the clamping force for rings needed on a PCP doesn't need to be much so there's that. BUT I used Nightforce rings on my 375 Cheytac and the NF 5.5-22x56 kept on slipping so I kept tightening and damaged the tube of the scope. I bought ARC rings which totally eliminated all slipping on the new 5.5-22, I was so impressed that I kept buying ARC's for the other expensive scopes and rifles. The way the ARC rings are designed, and seeing the evidence first hand was what sold me. Also every scope I've had in ARC rings rendered perfect tubes with no marring so I was able to sell the scopes for more.
All I'm saying is if a guy is buying expensive rings anyway then definitely buy ARC.
For looks alone I like the Seekins rings. They are sleek.
