Wilson Combat 1-Shot Extension Tube 12 Gauge Remington 870/1100 QD

Description

Wilson Combat built their reputation on making parts that get the job done. This one-shot extension tube does exactly what you need from a magazine extension: adds reliable capacity in a straightforward package. The parkerized finish matches standard 870 receivers, and the all-steel construction means it'll hold up to real use without flex or rattle.

The included extra-power magazine spring was engineered to feed rounds smoothly without jamming or sluggish cycling. The neon green high-visibility follower does double duty as both a functional part and a visual indicator when your magazine runs empty. That bright color makes it easy to see at a glance whether you need to reload.

Wilson Combat Extension Tube Installation and Setup

This is a single-piece design that threads onto your magazine tube, so installation is straightforward without needing additional clamps or brackets. The sharp knurling on the base gives you solid grip for hand-tight installation and removal. If your 870 has factory dimples in the magazine tube (most do), you'll want to file or swage them down smooth before installing the extension to ensure flawless feeding.

Quick Detach Sling Stud Feature

Unlike standard extensions with rear-mounted sling attachments, this model positions the QD stud at the front of the tube. That forward mounting point gives you flexibility in how you set up your shotgun's support system. The stud accepts standard quick-detach sling mounts for rapid attachment and removal.

The extension brings your total magazine capacity to five rounds, which is a solid practical upgrade over the standard four-round tube. Works on M870, 1100, and 11-87 models.
