I bought the 870 two years ago, new. It came with the synth setup but I just bought the wood stock and fore grip and installed that my self, simple enough. Now I notice once in a while, maybe two or three per 25 rounds, ill have to slam the fore grip hard to eject the spend shell. I no this is common with the 3 1/2 chambers, but I dont remember this happening with mine since i changed to wood, is it possible I over tightened the nut or its to loose? Is it something mechanically wrong with the gun? Weapon is clean, not a matter of cleaning it. Any input is appreciated!

Definitely check the magazine locking nut and tube to be sure it is correctly seated and snug. My bet is that you have one of the infamous rough chambers they have been putting out. It is easy to fix with a split dowel chucked into a drill with some 600 grit sandpaper wrapped around the dowel. Run the drill at a slow to med. speed and keep moving the dowel in and out of the bore - don't hold it in one place. I've been hearing a lot of customer complaints on this issue. If you don't want to do this yourself send it back to Remington. Certain brands of shells seem to cause more problems than others. But the gun should feed, fire and eject any make of shell.

kx592, You are correct that the issue described by drail concerns the chamber, which is a section of the barrel and not the receiver. If that is the problem, drail describes what usually cures the problem.
That said I am not so sure that your problem concerns a rough/tight chamber, but you may want to take a go at drail's inexpensive recommended fix. I did something very similar to my 870's chamber, but using 0000 steel wool instead of sandpaper.
Ther is also a possibility that the problem isn't with your gun, but the ammunition. What were you using that jammed.
That reminds me that you never completely explained what you meant by having to slam the fore end hard. Does the action open but fail to completely eject the hull or does it remained locke up with the slide refusing to budge unless you slam it to the rear?

If you had no problem with sticky extraction before you changed out the furniture, and you haven't changed the ammo you're shooting, I doubt the problem is in the chamber.
Open the action all the way and check the forearm on BOTH sides of the barrel to see if it's contacting the barrel in the chamber area. There's a 'swell' or taper up to the chamber diameter in that area, and if you failed to center up the fore-end correctly when you installed it and tightened it down, it could be rubbing on one side or the other. Might be the problem, or it could be something else, but that's what I would check first.
IMHO you're MUCH better off using a tool like the Menck ( http://www.brownells.com/.aspx/pid=8873/Product/ ) which allows you to install the forearm with the action all the way open, and makes it much easier to center up the forearm when you have the receiver right there to align it with.

I believe its fixed, I tore it apart, cleaned everything, sanded all burrs inside the receiver with 600grit, along with the in most part of the chamber, lubed and re assembled. Tried running 100 snap caps through it with no issues, only dummies so its not 100% but it feels much better so I would assume its good to go. Thanks fellas!
