Scope eye is all about eye relief and shooting angles, normally up hill is the concern.

If you end up with a custom built gun, they better mount your scope for you and they better make sure you have plenty of eye relief (given that you select a scope with at least 3.5" eye relief) !

I would mention to them that it is a concern of yours, just so they give you an additional half inch when mounting your scope.


BTW - ask around, it's happened to "almost" everyone..............and we are all still alive ! LOL
