Sure those scopes you had weren’t countersniper’sI had 3 USO SCOPES none of which ever worked long enough to even get them mounted on a rifle. I would simply go through the adjustments and they would fail. Lock up, lose focus, something come loose inside etc. I sent them back countless times. Literally incurred hundreds in shipping. They finally told me they had no idea how to fix them.
I wasted a couple of years fooling with them.
