Gave my m14 shorty a good douching yesterday and found this!
History, about 300 rounds of Chinese copper washed ammo, I never checked the spent casings to see if I was getting blow by at the primers, no other ammo has been fired in this m14.
Anyway, what are your take on this? And is this a full stop using this bolt?,
Thanks.

I would stop using that ammo 100%. however i would say from what i can see i would continue to use that bolt(as long as different ammo is used) i have fired many military rifles in the same conditions with nothing bad happen.

Hmm...
That don't look right.
That is were alot of preasure is building up.
Can I get a pic of were those numbers are under the lip on the side wall of the reciever?
Also is this the CanAm shorty rifle that is showing these issues?

Is it at all possible that it's just from corrosion, or a flaw in the original metal, and you just noticed it ? I'd really need to see that under a fairly high magnification magnifying glass with a lot of light to give you a better idea.

I've been shooting that Canada Ammo Norc 7.62x51 ammo for some time now, no corrosion from it.

Just as I thought.
I need that number under the reciever lip. Different will know what year of production it is and there for might give me a little more insight if it is a resualt of over pressure for tight headspace or if it is an old reciever from the bottom of the parts bin that might have one of thosse soft bolt's from back in the early 90's.
As I have come a cross a few of these "old" or "converted" M14 that have come from the CanAm shorty importation.

In piticular I was wondering if it was from the soft bolt era of Norinco M14's

Hi, Satain

The receiver was manufactured in April 1994. Since this is a Canadian import, the rifle was likely exported in 2007 or 2009. Is that correct? If you don't mind me asking for research purposes only, what is the receiver serial number?

Thanks,

Different
Ya Different,
There is an owner on Vancouver Island that I am thinking has one of those soft bolts. As I have recently examed from the CanAm imports that some recievers have been(Stuff deleted for public reasons)if you know what I mean. Also I have noticed that alot of these have been old stock that has been sitting around since the Clinton ban. But they have new barrels witch have really throw me for a curve ball. Plus some have the cali flash hidder while some have not been spot weld yet others have been. The ones with out the welds have what appears to be new manufactored flash hidders due to the lack of machine marks and also bayonet lugs.
below is a picture of what the person with what I think has a soft bolt is experancing with this reciever.
