It’s not as critical to have all of your scope’s elevation adjustment available. MPA’s mount has a unique NATO spec rail interface system that pulls the mount onto the top of the pic rail, which they say provides over 200% more rail contact than other competitive mounting systems that pinch the rail. One thing not covered here is how do you adjust the scope rings to optically centre the scope? Basically anywhere from 600 to 1200 yards you’d be within 10 MOA of the center of your scope’s adjustment range, which is where your best image clarity is. Appreciate the content. And don’t feel bad if you’re running an ERA-TAC. It doesn’t leave you wanting.
