Evolution Gun Works Mossberg 500/590/835 Picatinny Scope Base - Post-97 - Matte Black

The Evolution Gun Works Picatinny Scope Base is a one-piece optic rail machined specifically for Mossberg 500, Mossberg 590, and Mossberg 835 shotguns produced after 1997. The rail bolts directly to the factory receiver mounting holes, giving your pump-action or tactical shotgun a stable, repeatable Picatinny/Weaver-pattern platform for red dots, low-power variable optics, magnifiers, or any other modern aiming solution.

Built from domestic 6061-T6 extruded aluminum and finished in a non-reflective matte black, this scope base is engineered to handle hard-recoiling slug loads and defensive use without losing zero. Installation is straightforward and requires no gunsmithing - just four screws and a T10 Torx driver, with the mounting hardware included.

Whether you are running a reflex sight on a 500 home-defense gun, mounting a variable on a 590 for patrol or tactical work, or scoping an 835 Ulti-Mag for hunting, this EGW scope base provides a return-to-zero mounting point sized and contoured for the late-pattern Mossberg receiver.
