Like the title says. I got this shotgun new from Marstar as an exchange that I got from a Malfunctioning M-37 Tactical that I had purchased from them earlier. Turns out the 870 is no better than the M-37. It works fine when you cycle unfired shells in it, but the second you pull the trigger, the thing jams up. Generally, I have to ram the butt plate on the ground to be able to eject the spent casing. Obviously something is wrong. Now I'm passed the 1 year warranty, so I can't send it back. I've tried shooting various types of ammo in 2 3/4 and 3 in. and it always does the same thing. Although it seems to get a little better when the gun is hot, but as soon as it cools down, it's back to square one.

Now I'm wondering if it's something fixable and if it's worth fixing money wise. At this point I think I would rather see it disappear. I can't bring my self to sell it as a working gun, so I would have to sell this as a parts gun and take the loss. This sucks and it's the last Norinco POS I will ever buy! What should I do?

Well, I remember trying some Federal Buckshot and rifled slugs in both 23/4 and 3" and some Winchester 23/4 -71/2 game loads.I may of also tried some other stuff, but those I remember...
 
polish the chamber. Theres a few different ways, steel wool on a brush chucked in a drill or go to the auto parts store and pick up a hone. Use honing oil.
 
I've had a number of these through my hands and have never had a problem. These are a couple of things you could do:
The Norinco 870 is a clone of the Remmingtion 870, so go on the web and find detailled instructions of how to stripe the gun and what the various part should look like when working correctly or not. This should give you a start to see if any parts are bent, missing or broken.
2/ Try Marstar you maybe supprised, "if you don't ask you don't get."
3/ Take it to a gunsmith who will give you a free evaluation of the gun and cost of repairs. If a gunsmith cannot do this on an 870 he/she should not be in business.
4/ Try polishing the chamber with fine steel wool it often solves this problem on Remmington 870. The chamber is not undersized but is just too rough and polishing will help.
 
Well at least it lasted a year. I had a Norinco hp9-1 "Homeland Security" 12 gauge shotgun. Nice looking gun, but that is where it stopped. Had issues with it jamming up, then one day the whole action etc blew up on me. I returned it and picked up a Mossberg 500 Tactical. I will NEVER own another Norinco. The extra money is well spent to get something that is better built and will last.

I would say take it back, if a company values its reputation ( and they know these sites exist ) they should try and help you.
 
Blew up?

Fired hundereds of trap loads (600 i think so far) and a few boxes of 3" slugs (and 5 boxes of 2 3/4 slugs from CT) through mine, not one "jam" or glitch.

That's my impression of what the problem might be. I hope it's nothing more because I don't want to put one extra dime in that fiasco. I saw an ad in the CSSA magazine that someone was looking for guns for firearms training, it would probably be the most useful function this thing could perform...
 
Chamber could be rough and needs to be honed. This is also a problem with the 870 SuperMag, not just imported copies of the 870.

But the reason RePete mentioned the cheap Walmart trap loads is that they are notorious for sticking in tighter chambers, where as more premium shells often wont. I had older model, glossy, beautiful 870 Wingmaster that would gag on the cheapy shells that the new express would maw through without issue.
 
Ok, so this summer I "polished" the chamber area using a cordless drill with a cleaning rod and brush and it's pretty smooth now. I test fired the shotgun with some bird loads and I have noticed an improvement. The gun does not jam after each shot anymore and I don't need to ram the butt on the ground to eject the spent shell. My sister was able to shoot it even.

One thing that I've noticed when it does jam: the action stays locked as if the slide release mechanism didn't unlock after the trigger is pulled. Trying to slide the action forward before "pumping" seems to unlock the action.

Has anyone encountered this before? What could be the problem?

Why don't you send it to a Remington warranty station?

Because it's a Norinco. It was bought at Marstar, but I am passed the 1 year warranty. I'm trying to figure out the precise problem before I get on the phone with them. I don't know if they have spare parts laying around, like a trigger group, that I could buy from them.

Remove the trigger group and look at it. When the hammer is cocked you can push the slide release freely, you can inturn see how this allows the slide to release.
Then pull the trigger and let down the hammer(use your other hand to hold the hammer and let down slowly). You should be able to see how the plunger that gives the hammer its energy pushes up and pushes on a piece of metal which in effect releases the slide(the same as pushing the slide release).
Check these areas for any broken/bent or misplaced links/parts.
 
If the trigger group checks out ok, the the problem may be in the bolt or bolt carrier. Possibly the back of the locking lug is rough and not allowing free movement after firing.
Also check the fit between the bolt and carrier these two parts should mate together freely and the bolt should be able to slide along the carrier with little friction.
