The EGW HD Scope Base for the Weatherby Mark V rifle with a 9-lug bolt (brand part number 80702) is a heavy-duty Picatinny rail base machined with 20 MOA of built-in elevation, freeing up internal scope travel for long-range shooters chasing bullet drop at extended distances. Machined from aluminum alloy and finished in matte black, it bolts directly to the receiver using the included #6-48 x 1/4-inch screws and T-10 bit, no fitting or gunsmithing required. EGW builds the base ambidextrous and quick-disconnect ring compatible, so it works equally well for right- and left-hand shooters running QD mounts. It’s a natural upgrade for any Weatherby Mark V 9-lug action being built out for long-range work.

Frequently Asked Questions

Why choose a 20 MOA base over a flat base? The built-in elevation compensates for bullet drop at distance, leaving more of the scope’s internal adjustment range available for fine-tuning at long range.

Does it fit both right- and left-hand Weatherby Mark V rifles? Yes, the base is machined ambidextrous and mounts the same way on either action.

What mounting hardware is included? The correct #6-48 x 1/4-inch screws and a T-10 bit ship with the base, so no separate hardware purchase is needed.
