The Talley 850700LM is a one-piece lightweight alloy ring and base combo offering a simplified, rock-solid scope mounting solution for Bergara B14, Christensen Mesa, Christensen Ridgeline, and Remington 700 footprint rifles in long action configurations. Built with 20 MOA of built-in elevation to maximize long-range adjustment travel, it is fully CNC machined from aircraft-grade aluminum to Talley's exceptionally tight tolerances — no lapping required straight out of the box. The high-height ring profile provides additional clearance for larger objective lenses common on long-range optics, and the integrated one-piece design eliminates any possibility of misalignment between the ring and base. Mounting hardware and wrench are included, and it attaches to the receiver using 6-48 screws compatible with the standard Remington 700 footprint.
