Description
The Weaver Mounts 48333 Multi-Slot Base 417T is a 1-piece scope base designed for Mossberg 500 shotguns. Built from tough, lightweight aluminum and finished in matte black, it provides a solid mounting platform for Weaver-style rings, scopes, red dots, and other optics right on the shotgun receiver.
Weaver’s classic multi-slot rail pattern runs the full length of the base, accepting all Weaver top-mount rings so you can tailor your optic’s eye relief and position. The base also fits the Mossberg 590 receiver, making it a versatile upgrade for pump-action shotgun shooters.
Rings are sold separately.
