While I always thought I had a normal face... apparently I don't. 
The Problem:
For me, when I get a good solid cheek weld on an AR, and get up NTCH for repeatable eye placement I am staring at the back of the iron-sight body, or looking below the eyepiece of the scope.
If I measure (kinda hard to do yourself) I would say that my ideal sight height is between 0.75 and 1.0 inches, rather than the AR-standard 1.5 inches, depending how firm my cheek weld is.
If I go with standard AR height scope base, or irons I can get good eye placement by building up the stock with foam, but then I can't run the charging handle.
And lastly, I only have one "good" scope SWFA 3-15, that I want to be able to (even if it doesn't happen often) move between a bolt action with adjustable comb height (so this problem is irrelevant) and some ARs for hand-load accuracy testing where this cheek-weld problem really comes into play.
The Proposed Solution:
I was thinking I could buy a set of nice low rings such as TPS s-low which puts the centerline of the scope 0.82" above the rail, or their low which puts it at 0.925" and so long as the bolt-gun rail was picatinni spec I could pull it off the bolt gun any time needed and plop it onto an AR as mentioned above.
The objective bell is listed as 42mm which translates to 1.654 inches. Half of that is .827 which means .925" would have a 1/10th inch of clearance over an AR rail. With one of the non-full-length pic-rail handguards like ALG or SLR, the super-low rings would even work.
Once I get the scope centered/leveled in the rings it would be great to leave them on forever, and just remount the unit on alternate platforms so long as they all had the same spec/spacing on the mounting rail.
The Question(s):
Am I crazy? Should I just get a new face? Should I just let my whole head "free-float" above the stock?
Or does this seem like a viable solution to my problem?
Thanks all for reading and offering any suggestions you might have!
