The Remington 870/1100/11-87 extended magazine tube offers a straightforward way to boost your shotgun's capacity by one round. This single-piece design screws onto your existing magazine tube with a knurled collar, requiring no tools, gunsmithing, or permanent modifications to your gun.
Scattergun Technology built this tube from machined steel and finished it with a parkerized coating designed to handle regular use. The bottom loop provides a stationary sling attachment point without any moving parts or quick-detach hardware, making it simple and rugged. It ships ready to go with an extended-length magazine spring and a high-visibility nylon follower that tracks smoothly through the tube, which is especially useful when you're checking what's in the magazine.
This tube fits Remington 870, 1100, and 11-87 models in 12 gauge only. Depending on your shotgun's age and magazine spring design, you may need to remove some factory detents from the original magazine tube so rounds can pass through cleanly. Older models usually need less attention than newer ones. Once that's done, installation takes just a few minutes and the extension installs just as easily if you ever need to remove it.
You can hand-tighten the knurled collar onto your magazine tube by itself, though a lot of users find it helpful to secure it with a barrel clamp for added peace of mind. The single-piece design means there's no rocking or movement once it's threaded on tight. Most people report the fit and finish match well with parkerized shotguns.
This tube is designed exclusively for 12 gauge Remington 870, 1100, and 11-87 models. Other Remington models or gauges won't work with this specific extension. You can verify your model on the shotgun itself or in your owner's manual.
No tools are required. The knurled collar screws onto your existing magazine tube by hand. Depending on your shotgun's age, you may need to remove some factory detents from the original magazine tube so cartridges feed smoothly, which can be done with a rotary tool or file, but this is a one-time process.
Yes, the extension is designed to work without a clamp. The single-piece design is secure once hand-tightened. Many people add a clamp anyway for extra reinforcement or to mount a light, but it's not required for the extension to function properly.
If newer factory magazine tubes have dimples or indents designed to hold the spring retainer, these may need to be removed to allow the extension to screw on fully. Most users report this is straightforward with basic tools. Once removed, the extension threads right on.
