Tacstar Magazine Extension Mossberg 590 Plus 3

Versatile, Light Weight, Strong, Smooth Function, and Stylish! TacStar's modular shotgun extensions provide all of these benefits while adding additional capacity to your shotgun. The tubes are machined from tough 6061 aluminum, anodized matte black, and include a recess for a magazine/barrel clamp. Since both ends of the modular design tube have the same thread, it can be reversed to change the location of the recess for maximum versatility. Extensions are available for +2, +3, and +5 rounds over the standard factory magazine capacity (using 2 3/4" shells). The extensions come with a magazine spring which can be cut to your desired length and include a High Visibility Follower, which improves functioning and is easy to spot at the loading port. FeaturesIncludes High Visibility Follower Recess cut for magazine/barrel clamp (not included) Tough, Light Weight 6061 aluminum Matte black finish Long magazine spring allows fine tuning of fit/function
