Did I get cheated by BCM?

I ordered a DCM auto bolt group and when I got it today I notice something strange… The bolt is a MPI CMT. It it suppose to a BCM Bolt? IF that is the case what would be different than the CMT auto vs. BCM?

Thanks

Wow. I was going to say if you bought a bushmaster you were cheated plain and simple for several reasons.

If you got a CMT full auto bolt carrier and MPI bolt, you got pretty much all you could ever ask for out of a carrier and bolt.

Don’t feel cheated.

We don’t play these games here. It’s kind of obvious that you haven’t called BCM and found out what happened before popping this up on TWO internet forums.

Lock for now, pending deletion.
