Integrated Scope Mounts unitize the ring and base into a single, ultra-rigid unit Machined 7000 series aluminum that eliminates alignment problems and the possibility of a loose connection between bases and rings.
Use the Standard (low) ring height for scopes up to a 44mm objective with a standard barrel contour.
Use the Intermediate (medium) ring height for scopes up to a 50mm objective with a standard barrel contour.
Important: The listing for "A-Bolt" rilfes is for the original version A-Bolt and the A-Bolt II version only. Integrated bases and rings are NOT available for the AB3 at this time.
