Brand: Leupold 49864
Leupold QRW rings are engineered to retrofit any existing cross-slot base, thus converting existing mount bases into a quick-detach system. The spring-loaded levers can be "parked" by pulling each lever out, disengaging it from the locking screw. This allows you to adjust the levers to the desired position. Then, just release the levers back into the spring.
