Choate +2 Magazine Extension Kit for Remington 870 1100 12 ga with 18 in Barrels

Item Description

This listing is for ONE Magazine Extension Kit. Here are magazine extension kits for Remington 870 and 1100 shotguns manufactured prior to 1986, that are chambered in 12 gauge, and for any 870P Police series shotgun. Later version series 870, 870 Express, 887, and 11-87 shotguns that have dimpled magazine tubes and gear faced magazine spring retainers will require permanent non reversable modification to remove the dimples from their magazine tube in order to install an extension kit. Parts included are Extension Tube, Replacement Magazine Spring, and Barrel Clamp kit that anchors the tube to the barrel and prevents damage to the magazine tube’s threads. Tube and Clamp Manufacturer is Choate Machine & Tool of Bald Knob, AR. Spring manufacturer was Remington Arms of Ilion, NY, and Huntsville, Alabama. Construction is entirely steel, with polymer end plug in the extension tube. These tube’s collar sections are designed to mate with detent type barrel lugs that issued on Pre-1986 models 870 and 1100; and that issue to this day on 870 and 1100P series shotguns. This extension’s purpose is to add 2 more shells to the payload of an 18 inch or longer barreled Remington. Overall length of the tube itself is 6 3/8 inches. Magazine spring is extension type for this particular setup. Tube and barrel brace are one piece folded steel, complete with screw and forward sling swivel stud. The brace will likely leave bluing wear to the barrel and magazine tube over time. Finish is blued steel. Gross weight is 7 1/2 ounces, so this assembly will add between 5 and 6 ounces to the weight of the shotgun. Replacement pricing on this assembly often approaches $100. We’re offering them at a substantial discount.
