TRINITY Saddle Mount with 5-Round Shell Holder for Stevens 320 12 Gauge Picatinny Rail Aluminum

Upgrade your Stevens 320 12 Gauge pump shotgun with the TRINITY Saddle Mount with Integrated Shell Holder, designed to enhance functionality, accessibility, and performance. This precision-engineered mounting system provides a secure optics platform while keeping extra ammunition within immediate reach.

Constructed from lightweight aircraft-grade aluminum, this durable saddle mount features a solid one-piece design that straddles both sides of the receiver for maximum stability. The mount installs easily by replacing the factory trigger pin—no gunsmithing or specialized tools required.

The integrated 13-slot see-through Picatinny/Weaver rail allows attachment of optics, red dots, lights, or lasers while maintaining a clear sight picture. Included is a rugged aluminum shell holder that mounts directly to the rail and securely holds five 12-gauge shells (2¾″ or 3″) for quick reload access during hunting, range use, or tactical situations.

Finished in a sleek, satin black anodized coating, this accessory provides both reliability and a professional tactical appearance.
