First Look: XS Sights Remington 870 +2 Mag Tube Extension Kit

posted on March 25, 2021

XS Sights is introducing the new Remington 870 +2 Magazine Tube Extension Kit. The lightweight magazine tube extension is easy to install at home without the help of a gunsmith and increases the capacity of standard Remington 870 shotguns by two shotshells. The tube also allows for the mounting of additional accessories such as a sling mount. The kit includes a factory detent removal tool, a 45-degree 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.”

Made from hard coat anodized 6061 aluminum, the one-piece tube weighs less than traditional steel tubes yet still adds two more rounds to the magazine of your 870.  The tip of the extension has wrench flats that enable an easier grip while attaching the tube to the shotgun and also allow for the use of an adjustable wrench to get a snug fit. The extension measures 6 inches in length and will not extend past a 20-inch barrel on a traditional four-round capacity Remington 870 magazine tube.

The tube is machined to accept standard barrel clamps to allow for more support and provide the option of a sling attachment point. A short Picatinny rail can also be added to the clamp for mounting a tactical light or other preferred accessories. The tube is built to work with the factory follower, and aftermarket upgrades also work such as those from Vang Comp, Nordic Components and Wilson Combat. 

MSRP for the +2 Extension Tube for the Remington 870 is $110.00, and more information on this product and other gear from XS Sights is available at
