I was shooting my professionally assembled( not by me:)) Norc 2007, USGI bolt with SA ball and the extractor came off. First time that happened to me. Fired 2 rounds then the fun stopped!Firing pin looks fine. The 2 ejected shell caseing look normal. The extractor was just lying on the bench along with the spring.Extractor looks o.k. Is this the result of a faulty magazine? This is after about 200 rds fired after getting rifle built. Trying to decide whether to put all new innards in or just put the old ones back in.I'd rather have the old extractor fly through the air into the tall grass, rather than a new one if this is going to happen again right off the bat.
 
Normal. Happens every now and then with the m14 platform. Out of the 2 thousand of rounds I've put down range, I've only had this happen to me 3 times. It will only ever do that on mine, when using steel case ammo, and it hasn't occurred since I stopped using MFS. Just pop everything back together and you are good to go. If you have a 30-06 casing or a bolt tool, this can be done in 5 minutes or less. Its useful to have a spare parts kit handy at the range just in case this happens again.
 
I noticed the same thing with steel cased. It has happened 2x to me but i was shooting both brass and steel, both times it was on the steel.

Things that make you go 'hmmm...'
 
Hmmmmmm, pretty sure I know that rotten scoundrel that built that rifle ;)
It happens.... A couple times to me this year in different rifles.

Inspect back of extractor where the detent engages. The round recess in extractor should not be deformed or gouged. If it is, replace it.

Next, inspect detent and if the little ball on the end of the spring is gone, deformed or it's stud that engages spring is bent, replace it.

A magifying glass of sorts comes in handy here.
Shoot me a p.m. if you have any troubles Big Bear.
 
Much appreciated!

Looks ok, I'll let you know how it works out, thanks for the sentiment though.Have a great day, back to work for me:(
 
Lol, just be thankful that said parts didn't end up forever lost on the range Luke mine did :p

Other rifle related causes of spitting extractors would be a weak or tired ejector spring. The ejector spring gives the tension required to hold the extractor's post/stud in place and works hand in hand with the detent to keep the extractor in the bolt where it should be ;)

And Don, if yer headin north hunting, bring a quad or dirt bike, I have some BIG mulies out back and yer welcome to stay a few days. We moved from when you stopped in last.
 
tie one to a tree for me

I'm going to break down and get me a quad this year so I just may wander through your neck of the woods. Big mulie is top of my most wanted list. Thanks for the advice, now for some time to go test the bolt out.
 
Put it back together, ran 30rds through it no problem.... strange, guess I'll take it out on the long weekend and shoot it alot to see if the gremlin's gone for real.
 
Do you have any theories why this would be the case?

Do you think the steel cases were " stickier". ie. harder to extract?
