870 extractor replaccement

[Ebow1]

Long story short, I need a new extractor for my 870 express magnum. I'm looking at one on midwayusa right now, a 12 gauge 870 "marine magnum" extractor. 2 questions, is this interchangeable with mine, and is the marine magnum a non MIM part?

[Ebow1]

Too late. Just ordered it.

Who are you going to get to replace it?

I've got a busted extractor on one of mine. I have the part but don't really know who to go to to replace it.

I found a video online. Very simple process I found out. Remington 870 Extractor Replacement (How to Install non-MIM Extractor) | Rem870.com

My mistake, My ejector is broken, Not the extractor.

just out of curiosity, is this a common problem with 870's? I rarely shoot my 870 so I'm not overly concerned but I didn't know if this was something I should look out for.

Nah, no more so than most any other gun.

My 870 will not let me eject the spent shell and rack another one. Is this the same issue or a different one? Should I send it back to Remington? I purchased this gun passed spring!

Meaning it's "locked" after firing? Or it racks back leaving shell?

If the first, and a new 870 Express, probably needs chamber buffed some. Seems the new ones aren't always up to snuff with finishing, might be burr or rough area there. Also seems to happen more with the cheaper low brass shells.

If you mean it does rack after firing but leaves shell in chamber, then yeah, it could be extractor prob.

TLR-Like OhShoot said, my problem was a burr in the extractor. Cheaper shells like Rio do make the problem happen more often but the source is the extractor. Specifically, it was leaving shells in the barrel, not even pulling spent shells back into the chamber, loading a new shell into the empty chamber but then unable to rack it due to the spent shell still in the barrel.

Mine becomes locked after firing. My 870 was manufactured in 93' .....and yes I bought it "New" this spring (there's a thread about that). It is the Super Magnum.

Yeah, I remember now, the "new old stock" one.

Well, fired shell is sticking, extractor is good, holding tight, that's why you can't rack it back.

If it's still that way, (assuming here that IT IS ABSOLUTELY POSITIVELY A SPENT ROUND IN THERE FOR SURE, RIGHT?) hold forearm and smack butt of gun on something "firm but soft" like solid grassy ground or carpet on floor, that'll generally pull it out without having to disassemble, although you'll need to get barrel out to do the following anyway.

The standard fix stated by others I've read is to simply smooth out chamber -- I guess you could use steel wool, but get more advice on this as I'm not sure what grade is effective but still safe. You might be able to feel a specific burr somewhere in chamber with finger (or not).

Another way that I've read several times, is to superglue part of Scotch Brite pad around a wooden dowel, chock it in drill and do chamber that way. Maybe just a brisk session by hand might even do it, dunno. Clean well to remove all grit, of course.

Oh, here, this should provide some choices:

sticky 870 chamber - Google Search

Again, you may find it's only one brand of shells that stick, and likely low brass ones, but you might as well do this, as an 870 should run anything. Seems to be quite common anymore with current ones, somewhat surprised one from '93 has the problem, but things happen.

It must have been the ammo. It was jamming with Rio 12ga ammo. It cycled fine with Winchester the other day!!

I'd still buff that chamber out. Should run anything.
