The Lyman Plus 3 Magazine Extension is a black aluminum tube designed to bolt onto the magazine of your Mossberg 590 shotgun, extending its capacity by three rounds. If you run your 590 for home defense, clay sports, or tactical training, adding tube capacity without swapping guns makes practical sense—you keep the same gun handling and ergonomics while gaining reserve ammunition at the ready.
Built from aluminum, this extension is lightweight and corrosion-resistant, a sensible choice for a shotgun that might see hard use or harsh conditions. The Mossberg 590 platform has proven itself across decades of police, military, and civilian service, and Lyman has engineered this extension to integrate directly into that proven design.
Installation is straightforward: the extension bolts onto your existing magazine tube. No gunsmithing required. Once mounted, it adds three shells to your magazine capacity, which translates to more shooting between reloads and less downtime at the range or in a defensive scenario. For shooters who want to squeeze more from their 590 without buying a second shotgun, this is a practical, cost-effective upgrade.
