Browning 12511 X-Bolt Scope Mount System X-Lock Matte Black Aluminum 30mm Tube, Medium Rings

Browning’s X-Bolt Integrated Scope Mount System eliminates alignment problems and the possibility of a loose connection between the base and ring. To ensure the new X-Bolt has the most stable mount possible, this system features an all new X-Lock scope mounting system that uses four screws per base, replacing the traditional two-screw system. The scope bases being secured at all four corners rather than only held at the center of the base enables 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. This model is compatible with Browning X-Bolt rifles and has a medium ring height for scopes up to a 50mm objective with a standard barrel contour.
