    Product Compatibility Overview

    The Mossberg 590 Retrograde 12Ga 18.5" is a pump-action shotgun renowned for its reliability, robust construction, and classic styling. It features an 18.5-inch barrel, tubular magazine, and wood furniture reminiscent of military shotguns.

    Performance Upgrades

    • Trigger: The Timney Mossberg 590 Trigger offers a crisper, lighter pull for improved accuracy.
    • Barrel: Mossberg OEM barrels are recommended for reliability; consider a Mossberg 20" Heavy-Walled Barrel for increased capacity (requires magazine tube extension).
