I just ordered a ribbed forend for the 870 to replace the smooh polymer one on my 870 Express. How do you get the existing forend off to replace it with the new one?

Remove the forend assembly. There is a nut on the end with cutout slots. There is a tool made to fit sold at Brownells and the claw on a medium size hammer will fit. You can usually turn the nut with the claw of a hammer unless it is on very tight. Be very careful not to bend the rails. Put it in a padded bench vice with low pressure and put break free on the nut.

Good stuff MAX, the only thing that I would add is to saturate the threads of the fore end tube with liquid wrench a few hours before you try to spin the fore end tube nut. Sometimes rust will freeze these parts:(.

If it is a wood fore end be careful not to snap the fore end in two, this DOES happen, every time I said JUST a little more force, snap there went another one:eek:.

Good Luck on your project, and Be Safe

Anyone have a link to the tool I need? I didn't realize it was going to be such a deal. The forend on my old Mossberg 500 just slid off. I'm replacing the stock synthetic forend with a ribbed synthetic one.

Here you go,

This is a different one than came with my armorors package, but looks like it will work just fine.

Good Luck and Be Safe

Thanks, Bob. So I just fit the tool to the nut and turn, then slide the old forend off, slip on the new one, and re-tighten? I just ordered it.

Homerboy, I just replaced two forends. The 870 has a tool within it. The metal slide that the bolt rides on fits into the forend nut slots. I used this to turn the forend nut. It worked very well. Didn't cost a dime and nothing to order.

Really? So the slot that the bolt sits in is the tool needed to remove the forend? How does it work? Press the bolt between th two rails? Interesting. I'll see if I can make that work and will the cancel the order if I can.

I armor a lot of 870's I've never even thought about using the bolt carrier.

But sounds like a neat way to do it in a pinch

I will give it a try next time.

Yes, in a pinch it will work, however, I old wingmasters with "frozen" nuts, it can be a disaster in the making. That is why I ALWAYS suggest buying the right tool.

I just used a pair of needle nose pliers. Fit the two blades into the two notches on the nut, and it spun right off. The tool I just ordered (hope I can cancel it in time) looks like it won't even work. The forend extends past the nut so I don't see how I can fit the wrench over the forened to get at the nut anyway.

Excellent thread!!!! I have always taken the whole assembly off of the gun. Never too old or too experienced to learn. Thanks again.

By the way, the stock WILL fit on the 870 Express even though it says it is made for an 870, right? As far as I know, the only differerence betweeen the 870 and the 870 Express is cosmetic.
