Purchased an 870p last year. Wood furniture, smooth operation, coyote high brass patterns beautifully!

Just one problem...

The gun is missing the +2 magazine extension.

I've searched the EE to no avail.

Does anyone have a line on one or point my in the right direction to find one?

Any help would be greatly appreciated!

I went with Wilson combat. No complaints.

I'm hoping to find a Rem extension, but I'll definately keep that in mind!

I sell firearms produced by the finest child labor in the world, be it Filipino, Muslim, Mormon, Arizonan, or Texan.

Ebay has a couple of them now. But expensive!

The Remington Extension is distinctive with the front end that actually is the same diameter for a M7 Bayonet.

I’ve got one off of an 870 marine magnum. A little spray paint would take you a long ways.

If you want the distinctive Remington profile extension, you have to pay the money and find a used one.  If you are okay with a close clone, Tanks Rifle Shop makes a similar one, but it is missing the step down at the very end of the tube.  The step down does work with M7 bayonets.  I have a factory bayonet mount with the more rare bead sight and it uses the same tube with a extended clamp section.

@ihon
Thanks for the link!!
If I can't find an original, the Tanks version will be a great substitute!

These guys have OEM parts, they bought remingtons’ inventory out of bankruptcy

You just need to look around
