The Weaver #429M Top Mount Scope Base (brand part no. 48454) is a matte black, one-piece aluminum base machined specifically to fit the Remington 870. Weaver machines every #429M base to tight tolerances for a custom fit, so it seats consistently on the receiver without the rocking or play a loose base can introduce. The mount is designed to Weaver’s own ring standard for maximum clamping strength, keeping your rings and scope locked in place under repeated recoil, and it attaches directly to the receiver. It does not include rings, so you will need Weaver-style rings sized for your scope tube to complete the mount.
