Burris

Burris Signature Riflescope Rings also accept Burris Sign Ring Pos-Align Offset Inserts so you can virtually sight-in your gun without moving the riflescope adjustments. Lens systems perform at their optimum when all lenses are optically centered. By keeping the internal optics centered you'll see through the riflescope all of the clarity sharpness and brightness that the optics designers intended for you to see.
