My buddy purchased a Christian Arms Ridgeline FFT Ti

And a Nightforce SHV 5-20x56.

SHV - 5-20x56mm - Nightforce Optics

The SHV™ 5-20x56 is the most powerful of our SHV™ series and it performs beautifully at both close and extended ranges on varmints, big game, and for making tight groups on paper.

I'm going to mount the optic and help him get sighted in and DOPE, etc... but wondered if I would be good with a 20moa 1-piece rail, like a LaRue, and a set of low 30mm rings, or do I need med rights for the MOA, or should I not worry about the 20min rail and go straight and then be ok with low rings?

We would like to have rings with an integrated bubble level that is easy to see and doesn't stick out too far.

Thanks in advance.
