Default I purchased this bolt from AR15.....

Took it to the range last week and every lug was ripped off after 30 rds. It was checked by an armorer for head space, pin protrusion and such prior to shooting. I notified AR15 and they sent a FedEx return for it and offered me another bolt or my $300 back. I will take a refund. One of the most knowledgeable gun guys in the country said that it was most likely a MIM bolt and to stay away from them, anything ceramic coated throws up a red flag for him. Here is what it looked like, no other part of the gun was damaged
