Took one of my AR`s to the range yesterday. Luckily I took her apart to do my inspections and cleaning. I got to the bolt and it had a crack in it. I would have never noticed if I just wiped it down and not actually inspect the parts. She worked flawlessly and never gave in indication of anything wrong.

Lesson Look at your weapons, and how they wear with each other. That way from cleaning to cleaning you will be able to notice things like this.

Curious. Locking lug, cam pin hole, or other spot? Aprxmt rnd count?

Obviously I'm not the OP, but I'm going to guess the crack was at the back of one of the two locking lucks adjacent to the extractor. That's where almost all bolt heads crack first. I've also seen cracked lugs go for another 3000 rds or more before breaking off and they usually only affect function if they break off and hang inside the barrel extension & keep the bolt from going into battery or they get into the fire control.
