Barrel length? This is a common issue on 10.5" barrels and shorter.

AR bolts are consumables. You should get several thousand rounds out of a high quality bolt on a 16" rifle, but they're going to fail eventually. Cheaper bolts will generally fail faster.

Regular fire, or you using it like a bullet hose?

Quality of parts unknown
A young man asked me to figure out why his gun would not eject and I found broke bolt
No idea how he used it
I suspect it was ran hard

I'm not sure what else you are trying to gather about this then. It's broke. LOL

I was curious if this is a common problem
Thanks for the info

Yes, fairly common issue in cam pin hole on lessor quality bolts. Luckily a 5 min fix and pretty inexpensive.

This is common in bolts that have excessive clearance between the cam pin and bolt body. Not always a "cheap" gun problem either.
