Versatile, Lightweight, Strong, Smooth Function, and Stylish! TacStar’s new modular shotgun extension tubes provide all of these benefits while adding additional capacity to your shotgun. The tubes are machined from tough 6061 aluminum, anodized matt 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.  

This extension is +2 rounds over the standard factory magazine tube capacity (using 2 ¾” shells). The extensions come with a magazine spring which can be cut to your desired length and include Tacstar's High Visibility Follower, which improves functioning and is easy to spot at the loading port. Fits Remington 870 shotguns.
