Browning X-Bolt Base/Ring Matte High

"Securely mounted optics are essential to the accuracy and precision of any rifle. To ensure the new X-Bolt has the most stable mount possible, it features an all new X-Lock scope mounting system that uses four screws per base, replacing the traditional two-screw system. The benefits are obvious, with the scope bases being secured at all four corners rather than only held at the center of the base, allowing for more accurate placement of the bases on the receiver. This revolutionary new X-Lock system holds the base tighter to the rifle than ever before. Integrated Scope Mounts unitize the ring and base into a single unit machined from 7000 series aluminum and eliminate alignment problems and possible loose connections between bases and rings. Choose from integrated mounts in Standard, Intermediate and High rings for both 1"" and 30mm diameter scopes in gloss, matte and nickel finishes."
