This is a great product. 07/03/2014

Five minute installation on my 18.5", Rem 870, lightweight, 20-gauge. Perfect fit!

Installation tricky 17/05/2013

This kit will extend the 4+1 Rem 870 shot magazine to 9+1. The trick to successful installation is grinding the stop in the Rem magazine smooth. Otherwise the stop will catch upon loading shells. Dremel grinder will do the job...grind slowly...

How to get the edge on the bad guys 15/12/2011

So simple to add on (even on the newer version) to the reliable 870 series of shotguns.
Take that plug out, pop in the new spring and screw on the extension.
You're now ready to surpise the intruder with an extra 3 shots just in case they decided to hold a family reunion at your home.
Don't let them get away with it.
You can load a few light loads of bird shot and follow up with good old buck shot if they don't get the hint.
With the extension you don't have to worry about reloading so often. Some extra rounds in a butt stock holder and you're ready for swarms of bad guys or zoombies, whichever haunts your quiet neighborhood.
Price is less than the Remington stock one and these extensions work just as well, if not better!
I have them on all my 870s, both 12 Ga. and 20 Ga..

Definitely recommended

Great upgrade 11/03/2010

It took nearly five minutes to install the extension on an 870 Express not burdened with the internal ratchet system that would require drilling or grinding out the detents in the magazine tube. That included cleaning all the reddish-brown grease out of the extension.

The finish matches the matte finish of the shotgun fairly close. The tube threads down as tightly as the magazine cap it replaces without any slop. It seems to be more dent-proof than the factory tube. The provided clamp locked up well on the 20" tapered barrel and larger-diameter extension tube behind rifle sight ramp. The three-round tube extends out exactly to the muzzle. Choate also includes an orange, plastic follower that is an improvement over the short, flimsy factory part.

Minor points: The extension doesn't come with instructions, and the clamp doesn't ship with hardware that would allow one to do away with the attached sling swivel loop if not needed.
