The XS 870 Magazine Extension Tube Kit adds two rounds to your 870.

The shotgun remains one of the formidable weapons extant for duty and defense. But it also retains an age-old problem: it’s seemingly always running empty. For Remington 870 fans, XS Sights just released a new product to help combat that problem. The XS Remington 870 +2 Magazine Tube Extension Kit provides a DIY accessory to increase onboard capacity.

The XS Mag Tube Kit comprises a lightweight magazine tube extension system. It increases the capacity of standard Remington 870 shotguns by two shotshells. Additionally, it enables the mounting of even more tactical upgrades. The kit comes with a factory detent removal tool, a 45-inch Wolff 12-gauge extended spring and the +2 extension tube.

“This is a great product for shooters looking to expand the versatility of their standard four-shot 870,” said Zack Kinsley, Marketing Manager for XS Sights. “We have sold the tool to remove the factory detents for years and decided to provide a complete system that is simple, lightweight, and allows for personal preference tactical upgrades while installing the tube.”

The extension tube utilizes hard coat anodized 6061 aluminum. The one-piece tube weighs less than traditional steel tubes, according to XS Sights. The tip of the extension includes wrench flats for easier grip during install. Measuring six inches overall, the tube will not extend past a 20-inch barrel on a traditional four-round capacity shotgun tube.

The +2 extension tube kits adds rounds, but also surface for adding other accessories.

The tube accepts standard barrel clamps to allow more support. It also provides the option of a sling attachment point. A short Picatinny rail can also affix to the clamp for mounting a tactical light or other accessory.

The XS system accommodates factory followers, but it will work with aftermarket upgrades as well. Tested clamps and followers include Vang Comp, Nordic Components and Wilson Combat.

The XS Remington 870 +2 Magazine Tube Extension Kit retails for $80. For even more info, please visit
