    When you rotate it to the Auto position and pull the trigger, does it act like it's on safe?

    The most important would be the trigger and disconnector. If they were full auto along with a full auto selector the hammer would follow/slam fire and possibly run full auto for a few rounds.

    I'm pretty sure that ATF says any part "solely" usable in a FA gun is illegal, that would be the auto sear in the case of the M16, plays into the M16/ AR bolt carrier question. State laws are another matter.

    The definition of machinegun also includes a combination of parts from which a machinegun can be
    assembled if such parts are in the possession or under the control of a person. An example of a firearm
    meeting this section of the definition is a semiautomatic AR15 rifle possessed with an M16 bolt carrier,
    hammer, trigger, disconnector and selector
    . If the semiautomatic AR15 is assembled with the described
    M16 parts and the rifle is capable of fully automatic fire, the weapon possessed in conjunction with the
    M16 parts, whether assembled or not, is a machinegun as defined.

    Most likely the hammer will simply follow the carrier closed without the auto sear to delay it. Last time I saw one that did fire "automatically" without the auto sear was one the ATF taped up to delay the hammer.

    So let me reiterate this one more time. I am pretty sure that installing a full auto FCG would only be an issue should the weapon indeed do so.

    Now, I can verify 100% that if you install a full auto trigger, hammer, disconnector and selector lever in your weapon it will fire at a minimum in bursts and even full auto.

    I have video demonstrating this, but I don't feel like uploading it to the net. In any case you are treading on thin ice and it would surely suck to end up like David Olofson.

    Yes. It won't fire once it rotates past vertical.

    Sorry, but I have seen it done on confiscated guns. They did fire a few rounds and then stop.

    Iraqgunz mentioned Olofson in his post. Olofson's gun had f/a parts minus the auto sear which would be the same situation I described. (the f/a hammer operates the same as a semi hammer if an auto sear is not installed and a f/a bolt carrier is merely added weight without an auto sear.) At the range, with the selector in the f/a position, Olofson's gun, on more than one occasion, fired 3 to 4 round bursts before malfunctioning. That is why law enforcement was notified in the first place.

    ETA:

    Please go to page 9 of the below linked PDF to find a statement of facts in Olofson case. These facts are agreed upon by both sides. That day, at the range on more than one occasion Olofson's gun fired 3 to 4 rounds f/a then malfunctioned.

    Contact LMT. I had a BAD-Ambidextrous safety that would rotate a full 360, they sent me a new core, and no more problem. It sounds like a fluke.

    Sound like a semi safety and for some reason the detent is not preventing it from rotating past semi. Check the length of the spring, detent and the hole in the grip the spring goes in.

    Why don't you Google full auto selector lever M16 or similar. This will show you the difference between an auto and semi- or in any case it will help you determine what you have.

    This may be a simple issue of something not making proper contact.
