Nice!
Is it hard to get a good cheek weld with your Aimpoint up that high? I think Larue/ADM make lower mounts- if you ever start to dislike the height.
I just put that picture in paint and the very bottom of the optic is about the same level as the top of the FSB, so needless to say, it wont co-witness.
No. You need a low mount for the aimpoint to co-witness. I have been playing around with both the LT-150 and LT-152 and haven’t made up my mind as to which one I’m going to keep.
