The EGW HD Scope Base for the Weatherby Mark V rifle with a 9-lug bolt (brand part number 80700) is a heavy-duty Picatinny rail base machined to a dead-flat, 0 MOA plane, giving Mark V shooters a solid, precision foundation for a wide range of optics. 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 straightforward, precision-fit upgrade for any Weatherby Mark V 9-lug action headed to the range or the field.
