DA556 Not extracting

Hey Folks, purchased a DA 556 from you, and almost every shot it fails to extract. Have to pop a cleaning rod down into the barrel and pop the empty case out...


I've probably only put 20 rounds through it and about 18/20 have failed to extract.


Any thoughts...?
 
Is the bolt moving? Or is it not getting enough gas?

I've seen quite a few DA's arrive with paper plugging the end of the gas tube which would explain under gassing.
 
plus 1 for the paper plugging the gas tube

other thing to do if you havent already is clean the bore and chamber, DA and norinco often come extremely oily with a thick, almost greasy oil which could cause the shell to stick after it fires and expands in the chamber.

if the carrier cycles fine manually then its probably nothing to do with the buffer or buffer tube. only other thing i can think of would be A)check your extractor and make sure it looks alright and B) put some compressed air down the gas tube and see if anything comes out inside the bore, maybe theres some dried oil plugging the gas port
 
If I take the bolt out and stick a shell against the bolt face it seems to hold fine, but as soon as I put the bolt in the chamber and into battery, it will not hold on to the empty shell even if I manually push the bolt up hard against the shell.

And most times when I shove a cleaning rod in the barrel it doesn't take much force at all to shove that empty cartridge out.
 
how do the fired shells look? any over pressure marks? cracks? are the primers backing out or flattening in the primer pocket?
 
Mine didn't extract worth a damn either. I put one of those little rubber oring things under the extractor spring and it has had zero failures in 1400 rounds. Zero.
 
hmm, only other thing i can think, and this probably isnt it, but do you release the botl with the charging handle? if so do you ride it forward? if so dont, pull back and let it slam., i have seen many people new to semi autos (not saying you are) jam up their rifles because they baby the charging handle. try just using the bolt release on the side and then give the forward assist a good tap.

like i said i doubt thats it, i dont know your level of experience with firearms but i have seen many guys new to semis make this mistake so i just thought id throw that out there.
 
My Polytech CQ has that problem with steel cased ammo. 1500 rounds of brass cased were flawless, then I switched to steel cased, and am getting Failure to Extract. I suspect a dirty chamber. It's soaking in CLP right now.
 
I bought a DA556 last summer, had a similar issue. The bolt would go back and pick up the next shell. .....only problem was the spent case didn't extract or eject and the next shell would get rammed up the tail pipe of the spent one. I would remove the lodged live shell and cycle the charging handle, spent brass would pop out no problem. I as well tried a extractor up grade kit with a new spring and o ring.....didn't help. Someone suggested that I should try a different extractor claw next, think I might just cut my losses and buy a complete Daniel Defence bolt and carrier, should work flawlessly after that. Just sucks to spent an extra 500 on a cheap $600 rifle.
 
Had this problem with a 10/22 RIA... Get some solvent, not CLP, and drench the chamber... Let it sit for a bit, then take your trusty AR chamber brush, and give her a good scrub. With my RIA there was this grotesque black sludge that came out of it... rounds would be fed into the chamber, the claw would hook on, but the hot sludge would hold onto the casing... This may or may not be your issue... If not that, then possibly the extractor itself is buggered, either gummed up or not holding the round properly and needs to be replaced.

Not a gunsmith here... Just what I've noticed at the range and what have you.

If it's happening even after the first round, try giving the forward assist a good whack after you rack a round...

X5.
You can ignore all other posts.
Fixed this same problem on my 20".

Edit: I installed a DPMS ejector into my Norinco bolt at the same time.

Sorry to say folks, but hand over your money, I believe your wrong.

On the right is a Daniel Defence extractor and the left is the Norinco.

I believe we found the problem. Also have pics of the difference in size of the extractors. The DD would not fit on the Norinco bolt

Going to contact CanAmmo hopefully they can rectify the issue as there's literally only 20 rounds through the gun.
