Carlson Shotgun Magazine Extension Assemblies 10-shot Remington 870/1100

The Carlson Shotgun Magazine Extension Assemblies 10-shot for Remington 870/1100 adds genuine firepower to one of the most widely deployed shotguns in law enforcement and civilian defense. Built from blued solid steel, this threaded magazine extension replaces your factory magazine cap and extends shell capacity by adding 10 rounds to your magazine tube, making it an effective upgrade for patrol officers, competitive shooters, and home defense operators who need faster target engagement without reloading.

Construction quality directly impacts reliability under stress. The extension tube is machined from solid steel and finished in blued coating to resist corrosion during extended use. The kit includes a spring base clamp assembly and a high-visibility follower that tracks shell position, critical features for tactical reloads in low-light conditions. The threaded connection to your magazine cap ensures a secure fit; included instructions guide proper installation. Weight is minimized at 0.91 lbs, preserving the 870/1100's balance during extended tactical movement or extended range sessions.

This extension serves three primary user groups: law enforcement personnel running patrol 870s who need increased capacity for active-threat response; competitive 3-Gun and shotgun sport shooters where round count directly reduces required reload cycles; and home protection shooters who prefer magazine-fed capacity over tube feeding alone. The Remington 870 and 1100 compatibility covers the overwhelming majority of law enforcement shotgun inventory, making this an accessible upgrade for agencies and private operators using the platform.

Magazine extensions for pump and semi-auto shotguns remain essential for operators who need capacity without barrel or receiver modifications. The blued steel construction and proven Carlson design deliver reliability that matches the durability reputation of the 870 and 1100 platforms themselves.
