A factory Weatherby Picatinny scope base machined for the six-lug Mark V action. Using the correct base for your specific action is the single most common fix for mounting problems: it puts the optic on the bore axis where it belongs, eliminates the shimming and windage-cranking that plague mismatched setups, and gives you a full length of rail for ring placement and eye relief adjustment.

A one-piece Picatinny rail is also inherently more rigid than two-piece bases, which matters under magnum recoil. Straightforward to install with the proper torque and a dab of thread locker.
