Browning 123013 AB3 Integrated Scope Mount/Ring Combo Matte Black 30mm High

Integration means stability. 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. Important: Compatible with Browning AB3 rifles only. They do not fit original A-Bolts or A-Bolt II receivers.
