CZ 550 ejector issue

[dmancornell]

Hoping someone here might have some intuition on this problem.

My CZ 550 Safari in .375 H&H stopped ejecting today. The ejector is normally pushed down by the bolt when it is closed and pops back up along a raceway at the end of the bolt in time to kick out a spent shell. But now the ejector is stuck in the downward position.

I can reach in with a finger or screwdriver and push it back up. I can still feel spring tension on the ejector. It seems like something is holding the ejector in its downward position.

Anyone see this problem before?

Grit or debris would be my guess. If you can remove it from the stock, hit it with non chlorinated brake cleaner or any of the gun specific type of aerosol blasting solvents to free it up.

Yep!

If the spring is still sprung, and springy?

It's stuffed full of dirt and binding.

Clean & oil it lightly.

Thanks for the input.

I cleaned it a couple hours ago, still no good. The spring definitely has plenty of tension. It seems like there is a ball detent holding the ejector in the bottom position because it makes a clicking sound when I flick it back up manually. It must be held there so it doesn't drag on the bolt during cycling...

If there is a detent, the only way it can move back up to the top position is by catching the cartridge at the tail end of the bolt pull. So my current hypothesis is that the ejector is worn down so it isn't catching the edge of the cartridge base. Going to call CZ tomorrow to confirm. Hopefully that is it since it's only a $5 part.

update: CZ says the ejector is *constantly* under spring tension and there is no detent. So if it's stuck it is either dirt/grit or a bent ejector that need replacement.
