    I take pictures of my BCGs when they're still new/near new so thought I'd pull together pictures from the years into one place to compare them (things like staking, gas keys/screws, bolts and other features).

    In all four picture groups my Daniel Defense (no logo) is on top, then my first BCM, then my second BCM, then my PSA Premium (with logo), then my PSA MPI M16 BCG (no logo), then a PSA M16 BCG (not MPI, no logo), then a PSA 8620 BCG which is marked MPI. The last two PSA BCGs are not mine. As you can see the first seven carriers in each group are FA/M16. The very last photo in each group is an ArmaLite BCG, which in contrast has an SA/AR-15 style carrier.

    If anyone wants to add clear pictures of their BCG, feel free. It would be good to compare them.

    Again, here is the order top to bottom in each picture group and now I'll shut up and let the pictures tell the story:

    1 Daniel Defense (old unmarked version) (HPT/MPI but not marked, no logo)
    2 BCM #1 (marked HP/MP, with logo)
    3 BCM #2 (marked HP/MP, with logo)
    4 PSA Premium (marked HPT/MPI, with logo)
    5 PSA MPI M16 BCG (marked M, no logo)
    6 PSA M16 BCG (not marked, no logo)
    7 PSA 8620 BCG (marked MPI, no logo)
    8 ArmaLite BCG (not HPT/MPI, no logo)

    LWRC BCG with the advanced LWRC Bolt replaced by a regular MILSPEC bolt by the factory (they had production issues making enough of them as the machining is time consuming keeping SPEC is hard er than a normal bolt so and they had to throw away 50% of the advanced bolts hence the now delivery with regular bolt.)

    BCG is as shiny as it looks with a self lubricating alloy that feels slippery even when dry.

    Added another BCG to the first post...
    The very last photo in each group now is an ArmaLite BCG, which in contrast to the other seven has an SA/AR-15 style carrier.

    I'm just impressed with how many BCG's you have. I wanted to get a BCG as a spare for my Colt...can't find any Colt BCG so,I started looking for Daniel Defense or Bravo BCG's and none to be found.

    I bought mine over five years, as many others here have done, but did buy a PSA last month. BCGs are turning up now (even BCM and DD) so keep looking - and of course watch the Deals, Deals, Deals thread.
