Choose a " useable" mount as low as possible.
First of all, you need to know your base is a 0moa or 20moa. Besiclly, you want a 20moa or 30moa total (base + mount) cant angle depend on your normally long range shooting distance.
If it's 20moa base already, you can just choose a pair of 0moa scope rings, like "TPS, Seekins Precision, nightforce etc".
If you want one piece mount, depend on your optics, need to know
1. Objective lens size.
2. Erector Housing to main tube distance.
