Rifle Scopes Accuracy Intl. AXSR - which SPHUR mount?

[Diabolus]

I recently purchased an AI AXSR in .338 Lapua Mag. I am considering purchasing a NF BEAST and want to mount it to a SPHUR mount. I believe the AI rail is 20 MOA.

I'd like to get the scope as close to the rail as possible and because the rail comes from the facture with 20 MOA, should I stick with a 0MIL/0MOA?

Does anyone have any recommendations on which model to purchase?

Thank you
