3.0 Rating Built Well and the Price was Right - 1/4/2013
Reviewer: Matt
I bought this extension for my 870 with a 18.5" barrel. This extension holds three rounds, not two. It is a good three round extension, but it gets 3 bullets because I didn't want a three round extension. It sticks out past the end of my barrel. For this extension, you need at least a 20" barrel.

4.0 Rating Holds 3 rounds, not 2 as stated - 11/26/2013
Reviewer: Tim Allred
This is a nice item, but I ended up buying the ATI for use on my shotgun. This one holds 3 rounds, so does require a 20" barrel unless you don't mind it sticking out past the barrel by an inch or two. I kept this one because the spring is much more robust than the spring that came with the ATI version. I'll use this one on another gun I have with a longer barrel.

4.0 Rating It Will Work - 3/22/2014
Reviewer: Kent
I would not call it battle grade, but it will hold shells. There are better made Shotgun Mag Extenders out there, but this one does the job. It is made from sheet metal and the end cap is not made permanently to it. I like it and it functions well for me.
