Fierce Firearms machines this one-piece base for their long-action Rival and Rogue rifles with 20 MOA of built-in elevation taper. That forward cant matters once you start shooting past a few hundred yards: it hands the scope back a large slice of its internal elevation travel, so you can dial a long-range solution without running the erector out of adjustment and off the optical center of the tube.

Tying both ring positions to a single machined rail also keeps them perfectly co-planar, which is the other reason serious long-range shooters prefer a one-piece mount.
