Hi slim ,what do you mean exactly when you say eye relief to the scope ??
Hi mate, the distance between the scope and the nv lens, even with a bit of tape between the scope and the nv to block outside light i cant get a picture, just a blur ive tried adjusting the front lens on the nv but no joy so far, the nv works brilliantly off the rifle so cant wait to get it sorted on the rifle as your setup looks really good.
