Marlin 989 M2 Ejection Problems

[carbine85]

Anyone here familiar with this .22 rifle?
I'm having ejection problems pretty consistently. All of the rounds appear to extract and tumble around in the receiver, sometimes it stove pipes and it feed tries to feed the next round.
The ejector looks pretty good but I don't have anything to compare it to.
The left side extractor spring feels really light or weak. I'm not sure if this is normal or not. The right side is stiffer.
This one is from 1967 for what it's worth.

How long has it been since a full detailed cleaning has been done? 90% of issues with .22's are solved with a cleaning and lube.

It was torn down, cleaned and lubricated after I bought it.
It might be fickle with ammo.

If the rifle is clean the two possible things that come to mind are a broken ejector or gunk build up in the chamber causing sticky extraction. I have seen the chamber build up on quite a few .22's. It seems to happen with particularly waxy bullets that mix with the burnt powder. You can insert a dummy round into the chamber manually and see if it goes all the way in without help. If it doesn't then you have a fouled chamber.

I have a 989M2. Is the recoil spring and recoil buffer original? If so, try replacing them. That reality smooths out the action. Also, make sure you've really cleaned out the extractors extremely well. My 989 was completely filthy when I bought it a few years ago and I spent many hours detail cleaning everything to get the action reliable and smooth.

Follow the above advise on cleaning and lightly lube. Check the nylon buffer and make sure it's not cracking. When they start coming apart they can shift and interfere with the bolt rearward travel. They eventually shatter. Numrich(Gun Parts) has a great black rubbery replacement buffer. Make sure the ejector hook isn't bent out of position. It's in the mag well assy just above/behind your mag when inserted. It's easy to snag on patches or Bore Snakes. Also look the the edge of the chamber for a "ding" caused by dry firing. This can cause a burr that will drag on the case on ejection. If there is a burr do not file it off. There is a tool called a "chamber iron" that will push that metal back in. Sometimes a tapered punch can be used if not a lot of metal is dispalaced. Good luck.

The ejector can look OK and still not function correctly. Try bending the ejector in and up slightly, it won't hurt if it rubs lightly on the bottom of the bolt.

I made an adjustment to the ejector yesterday and it's much improved. It failed to eject 2 out of 7 with Browning ammo. CCI and Remington Gold all worked.
All parts are original but look great. The buffer looks fine. The extractors feel weak. I'm wondering if the extracted shells are just tumbling off the bolt face before they hit the ejector?
I can't do any more testing right now, the wife doesn't like me shooting in the garage

Ok, then tell her your moving to the basement. The garage is MAN'S territory. Just don't screw up the vehicles.
