Looking to buy another scope for Pdogs

You have 2 of the identical Nikons, but only one of them is giving you trouble? Can you swap the Nikons across and try the "good" one on your thumbhole stock rifle? Then you can see if it's the scope, or the rifle configuration that's causing the issue. If you find that it's the one scope, send it in to Nikon, and they'll either fix it or replace it. It's not unheard of for a scope to lose it's internal alignment.

I had a Burris black diamond do it once.

Ok so I have placed an order for the Viper PST FFP but I got it in the Mrad/Mrad format. Should I change that to the mil/mil?

Those are the same thing "Mrad" and "mil" are both short for "milliradian."
