Browning 12393 A-Bolt Integrated Scope Mount/Ring Combo Matte Black 1″ Medium

Integration offers strength and consistency. Browning's Integrated Scope Mount System unitizes the ring and base into a single, ultra-rigid unit. Machined from 7000 series aluminum alloy, they eliminate alignment problems and the possibility of a loose connection between the base and ring. A-Bolt refers to the original A-Bolt, the A-Bolt II. This system is not compatible with AB3 or X-Bolt rifles.
