Rifle Scopes Which Spuhr mount.

[Tikkablk]

Hi all,
I am after a Spuhr mount for my Nightforce ATACR 4-16x42 F1, sitting on top of a 20 moa pic rail semi custom rem700 338 edge.

Which one would be the better fit Spuhr mount SP 4001 or 4002?

4001 or 4011 with a standard stock.
If your on a chassis with a full length rail then you may want a 4006
4002 is to high unless you're going to run NV clip on
