Increased Round Capacity For Remington & Mossberg Shotguns

Short, screw-on magazine extensions add one or two additional rounds to tactical and sporting shotguns without increasing overall gun length. Replaces factory magazine cap with no permanent modifications. Machined from solid steel bar stock for a much stronger system to resist dents. Included sling loop can be installed for left- or right-handed shooters. Smooth-feeding, unbreakable follower is molded in bright green for easy inspection upon loading/unloading. Models available for Remington 870/1100/11-87 and Mossberg 590A1 shotguns.
