So, what do you think happened?

[yomomma]

I was going to do a poll but apparently I'm not worthy of that option.

I have my opinion.

Back ground. New gun. Under 200 rounds of appropriate ammo. Both lugs sheared. Brass is fine.

What's your opinion?

** not my gun **

Man that sucks. Did it end up like that or is that after trying to extract it ? Looks effed

Improperly heat-treated bolt in combination with a hot load?

 

[Bartok5]

Norinco metallurgy. Not the first soft Bolt Lugs and very likely won't be the last. A new week, a new Norinco failure....

What is the reddish stuff? Bedding material? Curious at why it appears to be around bolt roller. Other than that, I've got nothing.

Looks like over-greased op-rod.

Maybe poor or incomplete lug engagement.

What I was thinking
Bolt wasn't closed

Similar to my bolt failure a couple months back. Same thing after around 180 rounds, right roller lug sheared off.

What's going on with the op Rod it looks bent or out of place.

Were these guns bought from the same place? , what year import was yours ?
Might be a bad bunch if these are from a new batch of imports

 

[yomomma]

I think they are a new batch
