The only issue I've had with the wedges is that some scopes have a big turret area and the space between the scope and the pic rail is to small to use the wedges. A person might have to be careful not to torque your scope down on top of the wedge, you could damage something, so I would recommend watching that. Maybe move the wedge in and out every time you torque a screw a little. Also have heard of coins and playing cards being used. Each to their own…..shining a light through the objective onto a wall with a perfectly leveled cross drawn on paper has done me very well!
