Weaver 417T Aluminum Scope Base for Mossberg 500

The Weaver 417T is a two-piece aluminum scope base designed specifically for Mossberg 500 shotguns. This system provides a secure, low-profile mounting platform for attaching riflescopes or optics using Weaver-style rings. Machined from lightweight aluminum, it replaces the factory receiver mounting holes for a clean, stable fit.

Compatible with Mossberg 500 12-gauge and 20-gauge models, this base accepts standard Weaver-style scope rings (sold separately). Installation requires basic gunsmithing tools and the included mounting hardware. The matte black finish resists glare and corrosion in field conditions.
