New CZ won't eject

I'm quite pleased with the accuracy of my new CX 557 308 but quite displeased with it's failure to forcefully eject spent brass--or live rounds.  Even with a very brisk operation of the bolt about half the cases don't even clear the ejection port--the ones that do clear the port fall weakly just below it.  Removing the bolt and hooking a case under the extractor and then using the case to depress the plunger-type ejector seems to indicate that the spring under the plunger is strong.  I called CZ-USA in Kansas and they didn't have much advice other than to recommend sending the gun to them.  I hate to do it but but may have to unless someone might have a good idea on what is causing this.

... first, congrats on owning that cz ..... keep up the spirit, when you get it tuned , you will really like that beauty ...

if you are reasonably comfortable with tools ... you can try a couple simple things ...

first, make sure the extractor is working right .... i would remove the ejector and watch the action of the extractor ... also make sure the extractor is not getting in the way of the ejector action .  watch for losing the ejector spring when you take out the ejector plunger .

next, flush out the ejector hole and then see if the ejector slides smoothly in that hole ... i recently had a ruger 77 ejector gall and had to lap the pin and the hole ....  if everything looks good, cross fingers, reassemble and try again .

hoping this helps .  on a new ruger american 17 hm, the extractor was goofy and i had to polish everything that moved and clearance the moving parts ... about 0.001 ... working perfectly now .... that cz is going to be worth any little nuisance now .

I shipped the gun back to the CZ service center in Kansas City, KS.  Their web site says it normally takes 4-6 weeks for turnaround--and that won't start until Jan 2, as the whole place is shut down until then.  What a PITA!  If I wasn't so impressed with the gun's accuracy the first time out I'd be really pissed.  A fault like failure to eject should have been immediately apparent.  It makes one wonder what the guy who did the testfiring was thinking.
