Frequently Asked Questions
What optics are compatible with the 590S Optic-Ready receiver?
The Mossberg 590S Tactical Optic-Ready receiver is factory-milled to accept Shield RMSc-pattern micro dot sights for direct, low-profile mounting. Popular compatible optics include the Shield RMSc, Holosun 507K, and other sights sharing the same footprint. A cover plate is included when no optic is mounted, protecting the cuts from debris and maintaining a clean profile.
Can I use minishells or reduced-recoil loads in this shotgun?
Yes — one of the standout features of the Mossberg 590S platform is its ability to reliably cycle 1.75" minishells alongside standard 2.75" and 3" loads, thanks to its redesigned anti-jam elevator and dual extractor system. This means you can run higher-capacity minishell loads or standard defensive ammunition without changing any components.
Is the Mossberg 590S legal to purchase in California?
The Mossberg 590S Tactical Optic-Ready is a pump-action shotgun and is generally compliant for sale in California, as pump-action shotguns are not subject to the state's semi-automatic assault weapon restrictions. However, buyers should always verify current California DOJ regulations and consult with a licensed dealer like Goodland Guns to confirm compliance at the time of purchase.
