    Early Daniel Defense BCGs (around 08-09, when they first started hitting the market) do not have a DD on the carrier and no markings on the bolt.

    There are also BCGs that are GTG but with carriers that are unmarked, or the proof marked ground off. This is the case when a company gets their BCG's from another manufacturer. For example, I have an older M16 BCG that was made by FN, and the markings were ground off.

    The sword he sang a song of death,
    But could not make the sickle yield.

    If it was made by FN then it's not a Colt BCG. There was some debate as to how those FN items made it to the streets since they are not allowed to sell certain items commercially.

    FN carriers (at least those I have seen) are marked with an F. The bolts are marked MP F with an underscore under the F. DPMS carriers are marked with a D or two small dots.

    Just bought a supposed FN bolt that is MPF with the P being underscored. Ever seen one like this?

    No that's a new one. The one I have here at the house is marked MPF and also has the copper MILSPEC extractor spring and black insert. I wonder if yours is some kind of Palmetto deal?

    Check the various threads Del-ton bolts where the locking lugs virtually disappeared during some type of shooting malfunction. One was even attempted to be passed off and sent back to BCM.

    From what I saw the bolt markings were the same or similar.

    I won't know for a while (won't put the rifle together for several more years) but I bought one for my son's rifle; only one I could find after Sandy Hook. Looks like every other BCG. Proper staking at least.
