Weaver Mounts Top Mount Base #421M Matte Black Aluminum - Remington Model 7

The Weaver Mounts Top Mount Base #421M is a precision-machined scope base built specifically for the Remington Model 7 bolt-action rifle. Constructed from lightweight aluminum with a non-reflective matte black finish, this base delivers the rigid, repeatable mounting platform Weaver-style scope rings need to hold zero shot after shot.

The #421M is the rear base in Weaver's two-piece top-mount system, cut to fit Remington Model 7 rifles with the 4-hole receiver pattern (1999 and newer). It drops directly onto the factory mounting holes for a true no-modification install, keeping the optic positioned for correct eye relief and a comfortable cheek weld. Scope rings are sold separately, so you can match ring diameter and height to your specific optic and hunting setup.

The low-profile design keeps the base snag-free and pairs naturally with blued and matte-finished rifles. Compact overall dimensions of 0.80 in x 3.35 in x 3.70 in let the #421M integrate cleanly with the Model 7's receiver lines, while the rugged aluminum construction stands up to years of field use on the hunt.
