    It'll work. The disconnector "tail" isn't on a semi auto part, and obviously the auto sear isn't in the lower.

    From the footnotes

    “Four of the AR-15's fire control components were parts from M-16 rifles:  the trigger, hammer, disconnector, and selector switch.”

    I was just going to post the above. There was a whole lot more going on than just safety or selector.
    Stick


    Board policy mandates I state that I shoot for BCM. I have also done work for 200 or so manufacturers within the firearm community. I am prior service, a full time LEO, firearm instructor, armorer, TL, martial arts instructor, and all around good guy.

    So it had all the FA parts from a M-16 except the auto-sear? No wonder it would jam after a few rounds on "auto".

    Not 100% positive, but I still don't think that would produce anything even remotely capable of full auto. It's very common for parts kit builders to use all the original parts, save for the auto sear, and I've never once heard of one being full auto capable without the sear. At the very, very least, I think someone must have intentionally done some grinding or something.

    The auto sear only serves to slow the hammer drop until the bolt closes. They will fire more than one round per trigger pull without the auto sear, but not reliably - it is basically the hammer following the bolt. It mimics a malfunction more than a machine gun. At least that is what a guy told me - of course I would never try it and see what happens.

    This is correct. It will work. I have seen it done. The person I saw do this is no longer alive, so I don't think he'll have to pay for this act against humanity. But yeah... it works... not perfectly, but it will work.

    I would have to see some proof on that one.

    Like expert testimony in a court of law? Maybe you could write David Olofson in prison and see if he has a video.

    To the best of my memory, this video shows how the FCG parts interact and you can see the effect removing the auto sear would have.

    Exactly. I've seen it in person, and it works.

    And that knuckle head, Olofson, deserves it. Loaning out an Illegal MG to some booger eater who shot it at a public range? How dumb can you get?
