No, some are not. I bought one from 4 Guys Guns that is MPI/HPT, and it's not marked at all.

i really don't think mpi means much without the hp testing.
it's a 9310 bolt so it isn't milspec. just shoot the shit out of it. |

do you even know the meaning of what you just posted? OP marking is up to the manf, some do, some dont, some are req'd to look at the redx site they claim the bolt is tested to milspec. It isn't. On the mpi/hp testing i don't think mpi is worth much without the high pressure test. It's like getting your colon scanned without drinking the barium. |
