Ive seen pics of some with blinders atached to there hats, and some atached to there glasses. both of these bothered me. Im trying to eliminate the double vision I get after aiming for more than just a short time. I had never noticed this before while hunting or informal target shooting, but I did not stay on the scope as long. I did find that I could atache a thin piece of black foam around the scope tube just behind the rear mount that blocks my left eyes vision. the only down side is it takes a little longer to find my target. are there any rules against it being atached that way? or a better way? I had even thought of trying a pr of flip down sunglasses with the left eye blacked out. any ideas? #57
