I've only had a leg on the hammer spring break and I've only seen a bolt break right where it's thin going around the cam pin. thats it.

Even with an obnoxiously high round count through it, the only parts I've ever broken on my M16 have been 2 extractors.

The most common failure I've seen with the M16s was the hammer spring breaking.

I used to have a colt upper that was almost twenty years old. It had something like 20,000 rounds through it. I think the previous owner put 15,000 of that in full auto fire. Anways the bolt head cracked radially along the hole where the cam pin goes. The only way I really saw it was because it was hard chromed and I was cleaning the carbon off after a long day of shooting. That's when I replaced the barrel and bolt head with new parts.

I've replaced firing pin retaining pins, triggers, hammers, and gas rings because they were getting pretty worn, but nothing has actually broken (yet) on any of my ARs.
That said, it seems the bolt breaking where the cam pin goes through it seem pretty common. I've seen a friend's rifle do this during a 3-gun match. He wasn't a happy camper to zero a high-point stage. |

Hammer and trigger pins broke in half.
These were from a DPMS lower parts kit. The cause was probably the J-pin, that broke off from a Knight's trigger. This allowed the hammer pin to walk out and subsequent firing caused the hammer pin to snap. The off-center hammer probably caused the damage to the trigger pin as well. |
