The Wilson Combat vertical extension tube is built for serious use. These tubes come from Scattergun Technologies, which have been trusted enough to see field use with the US Border Patrol and Secret Service, so you know the engineering is solid. Your 870 or 1100 gets 2 extra rounds, bringing a standard 4-round magazine up to 6 total capacity in the tube.
What sets this apart from cheaper options is the construction quality. Every tube ships ready to install with an extra-power magazine spring that delivers consistent feeding through repeated use. The high-visibility neon green follower serves dual duty, letting you visually confirm an empty magazine at a glance and physically indicating proper magazine status during tactical reloads. A wave washer is included to help with installation and proper seating.
The steel construction features a durable parkerized finish that handles rough use without being precious about cosmetics. This isn't a competition-grade finish that needs babying, it's a practical coating designed to protect under real conditions. The tube mounts with a vertical sling attachment point on the bottom, giving you a clean configuration without side protrusions.
One important note: the follower isn't grooved to fit newer 870 magazine tubes. If you have a late-model 870, you may need to file down the detent dimples in your original tube to allow cartridges to pass smoothly into the extension. Many users handle this with a Dremel tool in about 15 minutes. The trade-off is worth it because the ungrooved follower actually works better in the extension itself, feeding more reliably than followers with grooves.
The included spring is intentionally longer than needed for flexibility. Some users trim it down depending on their specific shotgun, while others leave it as-is if they prefer a stiffer feed pressure.
Yes, it fits all Remington 870, 1100, and 1187 shotguns in 12 gauge. Note that newer 870 models have factory dimples in the magazine tube that may need filing to allow shells to pass into the extension. This is a one-time modification that takes about 15 minutes with basic tools.
The extended spring gives you flexibility depending on your gun and preference. Some people trim it down to reduce spring pressure, while others leave it for maximum feed reliability. The extra length also allows the same spring to work with +3 extensions if you upgrade later.
No, the ungrooved follower included works with your existing gun. If you want to keep your factory follower, that works too. The benefit of using the included bright green follower is quick visual confirmation of magazine status and smoother feeding in the extension tube itself.
Wilson Combat designs these specifically for field use and heavy handling. The extra-power spring is stronger than budget options, the parkerized finish handles real use without complaint, and the proven design has been trusted by law enforcement agencies. You're paying for durability and reliable feeding under stress.
