The Lyman 1082239 Plus 5 Magazine Extension for Mossberg 590 shotguns adds five rounds of capacity to your gun's standard magazine tube. Built from 6061 aluminum with a matte black anodized finish, this tube is light enough to keep your shotgun balanced yet tough enough to handle regular duty in the field or on the range. The modular design lets you reverse the tube to reposition the magazine/barrel clamp recess—a small touch that gives you layout flexibility depending on your setup and preferences.
This extension comes ready to work out of the box with a high-visibility follower that makes it easy to see your round count at the loading port and helps ensure smooth feeding every time. The included magazine spring is full-length and can be trimmed to dial in the fit and function for your specific gun, so you're not stuck with one-size-fits-all geometry. That kind of tuning is especially useful if you're running different ammunition types or have a shotgun that's been through the wringer.
Whether you're running a tactical setup, hunting, or simply want more rounds on tap before reloading, this extension gives your Mossberg 590 the capacity boost many shooters are after. It's the kind of practical upgrade that pays for itself the first time you need those extra rounds.
