Norinco 870 extracting but not ejecting shells

[Roddy]

I have a Norinco that is extracting but not ejecting low brass hulls, specifically Federal target loads. It has no problem ejecting high brass shells which seem to have a more pronounced rim.

One thing I noticed when comparing it to my Remingon 870 is that the action does not open as far. On the Remington the extractor is about a half inch past the ejection port when the action is fully open but on this one it is almost flush. I thought it might be that the bolt holding the stock on is in too far but I took the stock off ad it still won't eject hulls. I also tried a differant bolt but it had the same problem.

Have you tried swapping the bolt since you have a Remington 870? Trying it out with Remington factory spec internals will probably aid in the diagnosis

 

[Roddy]

Yes I tried putting the Remington bolt in the Norinco and it was exactly the same.

Here are some pictures if it helps:

This is what the shell looks like when it fails to eject:

This is how far back the bolt goes in the Remington:

In the Norinco it only comes back this far:

And as you can see the forend is not "bottoming out":

It has a Surefire forend on it if that could make a difference. This is the third Norinco 870 I have owned and this is the only one that has given me problems. I own two Remington 870s as well and I found the Norincos felt just as solid. It just seems like something is stopping the bolt from opening and I don't know what.

I feel a bit foolish as I had a very similar situation with my CQA and swapped bolts with my Colt AR to troubleshoot the problem, but swapping bolts fixed it that time!

Are you having an extraction or ejection issue? The description has attributes of both classes of problems.

Extraction issue => Action is hard to open after firing.

Ejection issue => Mechanism won't throw empty hull out the ejection port

Well unless I don't understand the term correctly I don't think it has extraction issues as the rounds easily come out the chamber every time they just don't eject out of the gun. It just seems like the bolt isn't opening far enough to properly eject the rounds.

I can't get your youtube link to work but if just covers polishing the chamber to keep rounds from sticking I don't think that will fix it.

In that first picture if I open and close the bolt ten times (lots of force, little bit of force, doesn't seem to matter) the shell will usually just sit there after or partially eject. I have to turn the gun sideways and shake it out usually. High brass hulls fly right out though.

URL is for polishing of chamber, and replacement of extractor. If the fired hull is falling off the extractor before it gets
pulled back against the ejector that is one of several possible explanations for the kind of problem you are describing.
If that is the case, replacing the extractor could solve your problem. (Borrowed bolt with known-good extractor is one way to confirm that diagnosis).

The ejector spring itself could also have a problem. Those are harder to diagnose/resolve.

I thought youtube links were okay, just not links to vendors that were not site sponsors. I see lots of imbedded youtube videos on here. I guess I should re-read the rules.

Like I said in my other posts the borrowed bolt with good extractor did not change anything so I don't know what's wrong with it. I have never had a round fail to extract so I dont think a burred or sticky chamber is causing any problems but I will polish it and see if it helps.

The only thing I can see that is weird is that action does not open as far as a Remington 870 and so the ejector is not able to put enough force on the round. It's almost like the reciever wasn't cut deep enough.

I was hoping it wasn't the ejector as I know they are very difficult to replace. I even tried bending it to make it work better.

Just tried it with a completely differant barrel and it still won't work with the low brass target loads.

Ejects black plastic dummy rounds and high brass rounds with authority but will not eject spent or unfired Winchester or Federal steel based shells. It's nice to be able to shoot on my property so I can go try it with live and dummy ammo.

Do you have a forend on it that is limiting the travel.

How long are the offending shells after they are shot, Longer ?

 

[Roddy]

I have tried it with a hogue forend and a Surefire forend. The forend does not appear to be limiting travel as the bolt bottoms out in the reciever. It bottoms out a lot sooner than a Remington bolt does though making me think the ejector isn't able to do its job properly.

Snap caps and heavy loads eject just fine. Unfired and fired low brass steel shells both have problems, but the longer fired ones seem worse. I have tried differant barrels, bolts, and forends. I have also tried it with trigger group installed and removed. I just tried bending the ejector to give it more power and that may have helped a little but not much. I am thinking I will just mail it to a gunsmith who specializes in 870s.

 

[supernova]

Is the ejector worn or bent? Slowly extract an offending hull and try to watch exactly what it does. Compare with something that ejects properly.

Yea, look at the ejector itself...clearly it is extracting as you observed.
