Adding capacity and reliability to a pump or semi-auto shotgun changes how you approach both range work and defensive readiness. A magazine extension is one of the most practical upgrades: it’s low-profile, mechanically simple, and directly increases the number of rounds available without altering operation or ergonomics.

CARLSONS SHOTGUN MAGAZINE EXTENSION is built to deliver that durability and extra firepower. Constructed of blued solid steel, this extension includes a spring base clamp and a high-visibility follower. The threaded tube replaces your magazine cap and lets you add extra rounds to the magazine—bringing a tactical advantage without complex gunsmithing. Priced at $73.99, this Carlsons accessory is offered in Various models to suit popular platforms.

Features and Build Quality

The extension’s blued solid steel construction prioritizes longevity and resistance to the wear of repeated loading cycles. The spring base clamp secures the extension to the magazine tube, preventing unwanted rotation or loosening during use. A high-visibility follower makes loading and immediate visual checks faster under stress or low light.

Why the threaded tube matters

Replacing the factory magazine cap with a threaded tube is the cleanest way to add capacity: it preserves the gun’s cycling characteristics while maintaining a factory-like profile. Because the part uses the magazine cap interface, installation often requires only basic tools and minimal handling time.

Compatibility and Installation

This extension fits a broad set of platforms, including Remington 870, 1100, 1187, and popular semi-autos such as Versa Max and V3-pattern shotguns. The product is made by Carlsons, a brand noted for shotgun accessories, and is listed under model Various to cover the multiple lengths and fitment options available. Installation notes: verify your magazine tube threads and overall length to maintain reliable feeding and to stay within local legal limits on capacity.

Use cases

Ideal for range shooters who want longer strings between reloads, competitors looking for a balance of capacity and handling, and defensive-minded owners who prefer more rounds in the tube without changing shotgun controls.

Field Use and Fitment

Expect a straightforward upgrade: the solid-steel body, spring base clamp, and high-visibility follower are designed for repeatable service. At $73.99 it’s a cost-effective way to increase capacity while keeping the shotgun’s core function unchanged.
