A Carlson's Parkerized Magazine Extension Tube for Remington 870, 1100, 11-87, V Max 12 Gauge is a straightforward way to boost your shotgun's firepower when it matters most. Whether you're running defensive drills at home, competing in shotgun sports, or training for duty, this extension threads onto your magazine cap and adds 10 rounds of capacity to your magazine tube. It's built from solid steel with a parkerized finish, engineered to handle repeated loading and the recoil of 12-gauge shotguns without flex or rattle.
The extension includes a spring base clamp with swivel stud attachment point, so you can mount quick-detachable slings for tactical or field carry setups. A high-visibility follower rounds out the package to help you track rounds and diagnose feeding issues. The design is simple and reliable—no modification to your shotgun needed, just thread it on and you're done. Carlson's includes clear assembly instructions, so setup takes minutes.
This tube fits the classic Remington pump and semi-auto lineup: 870 pump-action, 1100 semi-auto, 11-87 semi-auto, and V Max shotguns in 12 gauge. If you've relied on one of these workhorse shotguns and want to stretch your mission capability without swapping firearms, this is a no-fuss upgrade.
