Cz 527 .223 fails extraction

[Santiago85]

Hi! My rifle won't extract cases. Pushing and locking the bolt seems ok but, once I unlock and try to extract, the case stays n the chamber, either I fired or not, and the extractor claw misplaces as shown in the picture. https://ibb.co/QJzhpj3
I'd appreciate any help..

Looks like the extractors/bolts on the old Springfield 03 and M1917 Enfield rifles.

I don't think they'll do that (let the extractor move that far forward, but I don't have one sitting here to look at right now.

Does that extractor install from the rear and push forward?  My first thought would be the extractor is made wrong or the collar it locks into has a problem.

Never seen any of my old Army rifles do that.  Even when shooting HXP surplus (can be kind of HOT for the old bolt action rifles) the bolt is sticky to lift but the extractor has no problem pulling the empty out of the chamber.

HXP was widely sold by the CMP for use in M1 Garands and should be fine in the bolt action rifles, too.  But in some it acts like the pressure is enough higher to cause sticky extraction.  Sticky, not failed.

Sorry, for all the extra, just trying to say that in rifles with similar looking/operating bolts, even high pressure doesn't cause a bolt/extractor to do that (in my experience.

The extractor moved forward somehow. It should be in that groove. The extractor is a b i t c h to get off and then more so to get back on. It is not permanently attached to the bolt

As mentioned your extractor has moved forward. The top photo is a 527 bolt in the cocked position and all the bits and pieces in there proper places.                                                                                                                                 
                                                                                                                                                                                       
Bottom photo bolt is in the fired position and every thing in place. This just shows the extractor in it's groove and on the collar properly a bit clearer.

Hi! Thank you for your answers. I concur with all of you, and I understand how it "should" work... what I can't find is what is causing it to move forward. I replaced the extractor collar and nothing improved. Maybe the exctractor claw is too weak to keep in place?

[david s]

Not sure what to say. You've replaced the collar so I wonder if may be you got a soft extractor. On the original Mauser the extractor groove and extractor finger that rides in the groove are angled slightly and not cut at 90*. This way they cam together and pull together more as greater force on opening is applied. This is how a Mauser action will tear off part of the case rim instead of slip off. Is either the extractor groove or the part of the extractor that rides in the groove rounded over or chipped?  I have trouble under standing how it wont even pull an unfired case from the chamber if everything is in it's proper place. You have me stumped.

With the bolt out of the rifle, does the extractor drop/fit into that groove just back from the bolt face (like the one in David S.'s picture?)

If so, take a piece of fired brass, stick it in the magazine, insert your bolt into your receiver and slowly move the bolt forward.  Watch to see if the extractor pops up out of that groove as it chambers the brass.

Now I'm wondering if your rifle has the correct extractor or if it's (the extractor) made wrong.

That's how you get the extractor off the bolt - pull outwards on the extractor enough to pop that tab out of the groove on the bolt and then push the extractor forward, right?  The extractor can't move forward off the bolt like that if the tab is down in the groove.

It does...

Everything seems normal during all the process you can "see"..

That's what I can't understand.. maybe the extractor is too weak? It has no cracks dents or whatsoever...

I'm having the same issue with rifle, CZ 527 .223
I have bent the front and rear of the extractor to become more stiffer than what it was.
Refer to the video at https://www.youtube.com/watch?v=2Wa1bTLk70Y
Before bending the extractor, the extractor moved forward each time when pulling a round. It did not matter whether it was a live round, a fired casing or an old casing. After bending the extractor, the extractor tend to move forward less often than before, but it still happens from time to time. I can't bend it further, to get it more stiffer. By doing so, it is becoming difficult the pull the bolt fully back to eject the casing
