Remington 870 won't feed next round

I have a 60s vintage wingmaster that will not feed the next round from the magazine tube. I have cleaned and given the magazine tube a light coat of oil to make sure the follower is not hanging up. I can see the shell stop is slightly holding the edge of the shell and I can reach into the receiver with my finger and push slightly on the shell stop and the shell will pop into the receiver and can then be cycled.

Any ideas what the problem could be or a possible fix?

Could be an old, weak magazine spring that doesn't have the power to push the shell out properly.

Replace it with a new spring.

Check to insure the shell stops are firmly staked in place and are not loose.

Check the action bars to insure the small "ramps" on the bars are not burred or bent. These small ramp-like cuts are what operate the shell stops.
 
Could be wear to lifter and shell stop not allowing the lifter to push in far enuff to release next shell...

Put a business card against the shell stop and try to make sure the lifter stays on the other side of the card...

Cycle... If shell is released, you might can splay out the lifter sides a few thousandths...

Is there a shell latch on both sides of the reciever as in the 870 manual on the web site? They work at different times in the cycle.
Is there crud build up under either one?
 
Forgot the crud under the shell stop...

Being a Mossberg guy, I forget about the crud under them. I just drop them out and clean but they are staked in the 870 or is that different parts staked in place?

weak point

The staked shell stops are the "weak link" on the 870 design and can give trouble. In your clean and lube, did you pull the trigger group?

If the stops were loose you would have found out then, as they typically drop out with the TG. If you did not drop the TG, the stops could well be loose and you cannot tell.
 
Even if unstaked, 870 shell latches are pretty much pinned in place by the front trigger plate pin (part # 67 at http://www.urban-armory.com/diagrams/rem870.htm).

I'd suspect a buildup of crud behind the offending shell latch, or less likely an activating notch on the action bar on that side so worn it is no longer timed properly, if the gun has been heavily used.

An occasional new magazine spring never hurts... I usually replace plastic followers too, on used 870s. Brownells part number 080-000-083 contains a new spring and follower (for the standard magazine).
 
It's not juxt crud that get under the shell latch. I stupidly used a paper towel to clean out my magaazine. I later spotted, before it could cause any trouble, a piece do paper towel stuck under the tip of a shell latch. Now I just use a piece of rag.
