Add firepower to your favorite shotgun. These magazine extensions are constructed of blued solid steel and come with spring, base clamp, and a high visibility follower. The threaded tube replaces you magazine cap and gives you the ability to add extra rounds to you magazine. Easy to follow instructions are included. The magazine extension tube is great for home protection, competition shooting, and law enforcement. See chart below for the make/model and the magazine capacity.
Magazine round count is for the total capacity using 2 3/4" shells and 1 in the chamber
Remington extensions require removal of tabs in magazine tube on newer model shotguns
I used in snow goose hunting held 7 shot 3" in magazine and one in chamber for total 8 shots. It never missed cycle and there are a lot more extensions out there that cost more than double cost of this tube
