Scattergun Technologies 1-Round Parkerized Magazine Tube Extension w/ Quick-Detachable Sling Stud for Remington 870, 1100, 11-87 12 Gauge

The Scattergun Technologies 1-round parkerized magazine tube extension with quick-detachable sling stud is a straightforward capacity upgrade for Remington 870, 1100, and 11-87 shotguns that requires no gunsmithing or permanent modification. Simply screw the knurled, threaded collar onto the end of your existing magazine tube, and you've added one round of 12-gauge storage without altering the gun itself. This is the kind of practical upgrade that works whether you're running a home-defense shotgun, hunting waterfowl, or training at the range.

Inside the parkerized steel extension you'll find a high-performance spring engineered for the extended magazine tube and an unbreakable nylon follower with high-visibility coloring—the kind of details that save you trouble in low light or when you're reloading quickly. The quick-detachable sling stud is factory-mounted and ready to accept standard QD swivels, so you can rig up a sling without any secondary adapters. It's a no-fuss approach to adding both round capacity and practical sling attachment in one bolt-on component.

The parkerized finish stands up to hard use and wet conditions the way it should on a shotgun accessory meant to earn its place on a working gun. If you run an 870 or 11-87 and want to add capacity and sling compatibility without a trip to a gunsmith, this extension checks both boxes.
