HI

I am having some difficulty in quick acquisition, and am starting to think it might be the eye relief distance between me and the scope. The scope is a Nighteye 4-9x50, and the instruction leaflet says eye relief distance is supposed to be 3 and a quarter inches. This seems a hell of a distance, and would mean shifting the scope way forward, or holding the gun a lot further away! Surely this manufacturers distance figure is an "average" - it must vary depending on the users eyesight surely?
