Burris signature 30 mm scope rings - Burris 30mm Signature Universal Dovetail Scope Mount Rings

I purchased the scope rings along with a Bushnell 3–12×42 scope. I got the size medium rings and the height was perfect, just 1/8 inch off the barrel at its closest point. I set it up with the compensation rings adjusted to allow 20 MOA more elevation, as the Bushnell scope only had 25M MOA to start with. When all is said and done, I had 47MOA of elevation range. Enough to go 1000 yards if I want to with my 308. Very pleased with the quality of the rings and the instructions. The plastic liner rings also grip the scope firmly without causing any torque on the body of the scope. If I ever sell this scope, it will look brand new. No scope ring scarring.
