LPV Scope mount selection help needed, how much offset?

[Steve MKII]

So I want to get a Steiner P4Xi 1-4x24 for my AR15, but I'm not sure how much offset I need on the mount. I like to run my stock fully extended and I have a Magpul MBUS mounted on the gun (I'm willing to remove it if it's the only way I can get the proper eye relief with the stock extended). Eye relief on the Steiner is 3.5-4". Anyone know how much offset (if any) I need? I am thinking getting an ADM QD mount.

Thanks.

The MBUS should nest nicely underneath the ocular bell of the optic. The question about offset is determined by where you mount the optic and the amount of eye relief the optic has. A standard offset mount should be fine. The extended is also doable.
