The Lyman 1082236 Plus 2 magazine extension for Mossberg 590 shotguns is a straightforward upgrade if you need more ammunition capacity on your tactical or home-defense 590. This aluminum extension adds two rounds to your magazine tube, giving you extra firepower when it counts without requiring a different shotgun platform. It's built from aluminum for durability and corrosion resistance, and the black finish matches standard 590 aesthetics. If you run your 590 for 3-gun competition, training drills, or any high-round-count scenario, those two extra shells mean fewer reloads.
Installation is direct—Lyman engineered this extension to fit the Mossberg 590 platform specifically, so you know compatibility isn't a guessing game. The aluminum construction keeps weight down compared to steel alternatives, which matters when you're shouldering and cycling a shotgun all day. Black anodize resists corrosion and blends in with the rest of your setup.
Whether you're building out a 590 for home defense, running it at the range, or deploying it in the field, this extension is a no-frills way to expand your onboard ammunition without changing barrels or receivers. Simple, proven, and made for the 590 platform.
