Description
The Browning 12525 is a one-piece Picatinny scope rail engineered specifically for X-Bolt rifles built on the Ultra Magnum long action – the action length used for 300 RUM and 300 PRC chamberings. It provides a rock-solid mounting platform for any optic that accepts a Picatinny or Weaver footprint, while the integrated anti-cant bubble level sits directly in the shooter’s line of sight so the rifle can be leveled before the shot.
The rail is machined from aluminum and finished in a low-glare matte black to blend with the X-Bolt’s factory finish. A built-in 20 MOA cant angles the rail downward at the muzzle, adding elevation adjustment range to the scope’s turrets – a useful feature for long-range and extended-distance shooting where the factory zero may run out of dialable elevation. Because the base replaces the X-Bolt’s receiver-top mounting surface, the optic mounts directly to the rail; rings are not included.
