Scattergun Technology Remington 870/1100/11-87 Ext Mag Tube, Bottom Loop, 1 Rd

A Scattergun Technology Remington 870/1100/11-87 extended magazine tube with bottom loop gives you extra shotgun capacity right out of the box—no gunsmithing, no permanent modifications. Built from machined steel and engineered for 12 gauge shotguns, this one-round extension threads onto the end of your existing magazine tube using a knurled collar that hand-tightens securely. It's a straightforward, reversible upgrade that works with three of the most popular pump-action shotguns in America, whether you're running a classic 870, the semi-auto 1100, or the gas-op 11-87.

The real advantage here is the bottom loop. Unlike extensions that require aftermarket sling swivels, this one gives you a stationary attachment point molded into the base—perfect if you run a tactical sling or want quick, simple rigging without extra hardware. Pair it with the included extended-length magazine spring and high-visibility nylon follower (designed not to crack or wear out), and you get a reliable, long-term upgrade.

Scattergun Technology has a solid reputation in the shotgun community for no-nonsense parts. This extension is the kind of upgrade that appeals to hunters, competition shooters, and defensive-shotgun users who want more rounds in the tube without taking their gun to a gunsmith or committing to permanent changes.
