    Removal of the stocks (including disassembly of the gun) should take five minutes or so.

    The manual (downloadable from the Remington site in .pdf form here) describes removing the forend/rail assembly as part of the disassembly instructions.

    I'd be interested to know how you get the forend off of the tube, though, because it seems to be wedged on there pretty well on my 870 Express (wood).

    As for the buttstock, simply remove the buttpad (there are two holes in the buttpad with two screws underneath)


    and you'll need to use a large, long flathead screwdriver to unscrew the buttstock screw.


    End result: ready to install your new stock on.

    Remove the barrel. Then you have to remove a round nut that is between the fore end and magtube. It can be done with a long pair o needle nose an a lot of patience. Or buy the wrench. It is basically a piece of pipe with a pin that sticks out the side approx 1/8" on each side.

    If you look down there you will see what I mean. The wrenchs can be bought from a guy on eBay for approx 10 bux. Do a search on eBay for 870 wrench.

    a piece of steel rod bent to shape (horseshoe) makes a good tool for forearm removal.

    I would caution you against trying to remove and replace a forearm without proper tools. I've seen all manner of damage done by folks trying a DIY approach without having the correct tools. You can buy a proper tool for what it would cost for a 'smith to do it for you, and definitely for less than it would cost to replace the forearm tube/action bar assembly. I've seen those damaged beyond repair in the process...

    +1 on that.

    A number of people have taken the advice to try using a pair of needle-nosed pliers as a "spanner wrench". Sometimes, the nut is loose enough they get away with it.
    However, often the pliers slip and does serious damage to the very thin action bar tube and threads.
    New action bar assemblies aren't cheap.

    my off-brand 870 looked like a nightmare inside compared to my Mossberg 500. The Mossberg forend and bar assembly was so easy to remove that I pretty much did it on accident. The Rem model...eh, didn't even want to try.

    That's for sure.

    The nut holding on my 870 forearm was so tight that the "proper tool" bent trying to turn the nut.
    After straightening the tool three times the nut finally broke loose.
