I would like to change the wood to synthetic on my Remington 870.The stock is an easy removal but the foregrip/pump looks like it might have a special nut holding it on.Is this the case?Thanks.

Yes.

You will either need to buy a nut tool, or build an expedient tool.

Some people have used needle-nosed pliers, but if you slip, you'll do serious damage to the thin fore end tube.

A simple tool can be made of a flat piece of steel that will fit down into the fore end, and thick enough to fit the notches in the nut.

File a notch in the center so you have two lugs that will engage the nut notches.
Grip it with a pair of vise grips.

getting those forearms off can be a MAJOR PAIN, especially the wood ones.
you can buy a tool, but ive seen those things bend, you might have to consider a gunsmith to do it.

Buy a Surefire forearm and get the tool free

Its not that hard.


To use the tool, you must remove the whole assembly, the forearm, pump tube and feed arms......then remove the forearm from the tube.
You can't use the tool with it assembled since the mag tube is in the way.

You can use a flat screwdriver and work the two slots in the (almost a castle) nut.

Fieldstripping:
1) Remove mag tube nut (and mag spring)
2) Remove barrel
3) remove two retainer pins with a dull punch
4) remove trigger assembly

Here is the only tricky part:

5) Inside the rcvr, squeese the two arms that retain and release each shell from the mag tube. Simultainiously pull the forearm out.
The bolt should come with it.

6) Remove the forearm.

7) Take this opportunity to do some spring cleaning.

All that to use the tool.


I've done it several times with no tool. The torque required to install/remove the nut is low.

It is tempting to try to remove the nut without disassembling the weapon but do not do it, you can damage your slide. Take the time to disassemble your shotgun, you will learn a lot in the process and give you a chance to give your gun a thorough cleaning. The disassembly process is fairly easy and you will be glad you took the time to do it.
