Thread: Scope level what do you all think?

I get an A4 piece of paper, draw a line down the middle with a sharpie. Then I put the paper on the floor, sit the butt on top of the line and align the butt with the line (so the line dissects the butt top to bottom. Then look back down the scope (top down), and use the black line with the vertical on the scope. The hardest part is trying not to move the butt.
