Weaver #417M One-Piece Scope Base for Mossberg 500/835

The Weaver #417M is a one-piece aluminum scope base designed specifically for Mossberg 500 and 835 shotguns. It mounts directly to the receiver and provides a solid, low-profile platform for attaching Weaver-style rings and optics. The one-piece design eliminates alignment issues between separate bases and creates a rigid mounting surface that maintains zero through heavy recoil.

This base is machined from aluminum with a matte black finish and uses the shotgun's existing holes for installation—no drilling or tapping required. It's compatible with any Weaver-style rings and works with both bead and rifle sights. Mounting hardware is included.
