Carlson’s Choke Tubes 04506 Magazine Extension for 12 Gauge Remington 870/1100/11-87 shotguns is constructed of blued solid steel and comes with spring, base clamp, and a high visibility follower. The threaded tube replaces your magazine cap and gives you the ability to add extra rounds to your magazine.
The model 04506 measures 6.25 inches in overall length. This 7-shot extension allows the gun to hold 7 total shells with one in the chamber, meaning it adds 2 more shells to your firearm’s original capacity. Capacity specifications apply when using 2 3/4-inch shells; using 3-inch shells results in 1 less shell capacity.
Installation is straightforward—the extension simply threads onto your existing magazine tube in place of the factory cap. Remington extensions require removal of tabs in the magazine on newer model shotguns. This upgrade is ideal for hunters and sport shooters seeking increased ammunition capacity without replacing their trusted Remington platform.
