Product Description
Increase the capacity of your 12 gauge Remington shotgun with the Carlson’s Magazine Extension (04521). Constructed from blued solid steel, this threaded extension replaces your factory magazine cap to add additional rounds while maintaining reliable feeding. Each extension includes an extension spring, a base clamp with swivel stud (quick-detach swivel not included), and a high-visibility follower (note: some applications may require the factory follower).
