Gotcha

A red dot would provide the best eye relief as far as arms extended vs arms bent etc I would think
But the magnification on the ACOG would be nice though, I’m only familiar with the ones my beloved Corps was issuing in the mid 2000’s and they were pretty badazz on a M16 but I don’t think that style would be as good with super long eye relief.
Man I bet that is a pleasure to pack around in the woods! I need one
