870 mag extention

[exilefromhell]

Where can I get a mag extention for my 870 mag that is a good color match and will fit flush or close to flush on the 18.5" barrel that is on it now?

Thanks

Among other places, Brownell's at: www.brownells.com sell most of the available makes (Choate, Scattergun Tech, and Tac-Star). Most of these are available in blue (actually black) or parkerized, one of which will be a close match. For an 18" barrel you will need a 2 shot extension which will not be longer than the barrel.

There is also a plastic extension available elsewhere, but I can't recommend it.
