The rail mounting clamp is spring loaded and makes installation very easy. Large easy to grasp knobs for the rail mounting clamp make installation easy. The design of the butterfly clamping system takes a lot of the clamping pressure off of the scope tube and puts it back into the mounting system to help prevent any torquing of the scope tube.
