A buddy has a Remington Wingmaster 12ga shotgun that is not ejecting shells correctly.


Any guesses as to what is wrong? He says the gun is clean, and the shell doesnt get ejected when you work the action reward.

I had a friend that was having the same problems with his 870, and his extractor had fallen off.

Pumps are pretty simple, if the shells are being extracted but not ejected, I'd say it's the ejector.

How can I replace it and where can I find one?

Unfortunately, Remington 870 ejectors are NOT user replaceable.

The ejector assembly is riveted into the left receiver wall.
To change it REQUIRES a special riveting punch that can re-rivet the special double headed rivets.
A good gunsmith WITH the special tool can often do the job without having to remove the entire ejector assembly.  If not, you also have to have the receiver refinished since the rivets are polished flush with the receiver on the outside.

I suggest either finding a factory authorized gunsmith, or sending the receiver in to the factory.

Before assuming it's the ejector assembly, make sure it's not a broken or fouled EXTRACTOR.  A weak, broken, or fouled extractor may pull the shell out of the chamber, but can't hold it so the ejector can eject it.

If in doubt, either find a gunsmith or an experienced 870 owner and have them look at it.
The ejector is a two piece assembly.  The ejector itself seldom to never breaks, but the long, shaped flat spring does.
Look for the spring to be sure it's present and not damaged.  
Here's an exploded view:

The ejector is part number 13, the ejector spring is part number 16.

Again DON'T try to replace it yourself unless you can buy the special riveting punch AND learn how it's used.  Screw it up and you can ruin the receiver.

Take a CLOSE look at the EXTRACTOR assembly.  The extractor should be free to move, with plenty of spring pressure and the extractor hook should not be chipped, broken, or worn.
Often the extractor spring gets fouled up and there isn't enough spring tension for the extractor to hold the shell.
When it's extracted, the shell slips off the hook and the shell fails to eject, looking like it's the EJECTOR that at fault.

Thanks for your help.

If it is the extractor, would that be user replaceable?
