The Carlsons magazine extension is built from solid blued steel and threads directly onto your existing factory magazine cap, making it a straightforward way to boost your Remington's firepower without major modifications. This isn't a complicated installation either. The kit comes with a new spring, base clamp, and a bright follower that makes loading easier and helps prevent over-compressing the spring during use.
If you're running a standard 870 or 1100 with a 4-round capacity, jumping to 8 rounds makes a real difference for range sessions, clays, or competitive shooting. The extension works on the Remington 870, 1100, 11-87, and even some newer models like the Versa Max and V3. Just keep in mind that if you have one of the newer production shotguns, you may need to remove dimples in the original magazine tube first to seat the extension properly.
Solid steel construction means this isn't going to fail on you. The blued finish matches factory Remington shotguns, and the threaded collar screws on securely so it won't shift around during use. The high-visibility follower included in the kit serves a dual purpose: it helps you see where you're at capacity, and it protects the spring from getting over-compressed when you're loading fast.
People have had good success using these extensions for hunting, competition, and general shooting. The improvement in handling and balance from the added length and weight is something you'll notice, especially if you're doing any clay shooting or running through courses. It's a practical upgrade that keeps your favorite gun in action longer without frequent reloads.
Installation is relatively straightforward and doesn't require specialized tools. You'll need basic hand tools. However, if your shotgun has dimples in the original magazine tube (common on newer production 870s), you'll need to drill or file those out first before the extension will seat properly. Some owners cold blue the drilled area afterward to prevent rust.
Yes, it's compatible with Remington 870 Express models. The same dimple consideration applies here as with other newer production shotguns. The extension works with both 2.75-inch and 3-inch chambers, though you'll get full 8-round capacity with standard 2.75-inch shells.
You'll go from the factory 4-round magazine capacity to 8 rounds in the tube, giving you 8+1 with one in the chamber. This doubles your available ammunition before needing to reload, which makes a noticeable difference at the range, in competition, or on extended outings.
The blued finish is designed to match Remington factory bluing on 870s and 1100s. It should blend in well with standard blued shotguns, though the exact shade may vary slightly depending on your specific gun's age and condition.
