Mine broke tonight after shooting a few hundred SS109's. Here is a pic. My question is. I would like to know if there is a difference in Semi and Full Auto bolts. I know the carriers are different but would like to make sure I don't get the wrong one.

Thanks everyone. I'm not sure on what brand it was. I bought a old PWA and it was in it. So BravoCompany makes a good bolt? I guess I will be looking for the one that takes the best beating. Thanks again everyone.

Breaking across the cam pin hole is pretty classic. I'm using a Fulton bolt that lasted for several thousand rounds.

MPI tested, shot peened, all the good stuff.

I am not entirely sure if this is true but I believe Bravo Co. uses CMT MPI'ed bolts in their BCG's. I have both and the markings on both are identical. Both have an engraved CM marking and both have the same MP marking.
