I have a block of wood about 4 inches long a 1 X 4 attached to each end ...... the 1` x 4's stick up above the block of wood
each of the one by 4's have an identical v notch cut into them
I put the scope in the V's and look through it.....
I rotate it 180 degrees and then adjust the crosshairs
so that the crosshairs are in the center........
they don't change when you rotate the scope 180 degrees....
i usually have to rotate and adjust several times......
I usually put the block of wood in a Workmate and look through the scope at something 50 or 80 yards away....... like the windows on my neighbors porch.... or a post sticking up in the yard.....
