The Browning 12503 is part of the Browning integrated scope mount system. Made from the durable 7000 series aluminum, it features an in-built ring and base combo. This construction design leads to a supremely firm unit.
A major advantage of this system is its ability to avert potential alignment issues and the risk of a shaky connection between the bases and rings. Situating it apart is its tailor-made design to fit specifically the Browning X-Bolt Rifles.
