Question on FA parts for AR15

Ok, here is a situation.

There are 3 things needed for Full-Auto in an AR/M16 rifle.
1. Full-Auto bolt carrier group
2. Full-Auto trigger group
3. Full-Auto Sear or a Drop-In Auto Sear

I know that many ARs come from the factory with Full-Auto BCGs and the BATF had already stated that this was fine because there are other parts required to have Full Auto.

If you have a FA trigger group and FA BCG in a Semi-Auto lower, you still DO NOT have a Full-Auto rifle, you would need the FA Sear or a drop in auto sear.

I ask because I already have FA BCGs and would like to go ahead a get a FA trigger group for future spares (wanting to buy a M16 in the next year or so) but will not be installed.

Is this legal to have the two items in possession or installed if you only own a Semi receiver and you DO NOT OWN a drop in auto sear?


Thanks
Hulley

In a word... no. In fact "Hell No". You can find BATFE advice on this if you search, but here's the skinny:

You can force an AR to follow-fire soft (pistol) primer handloads with a selector set to "full" on one that has the full auto fire control parts. You don't need the full auto bolt carrier to do this either, as it only trips the sear if a sear is installed. So: The fire control parts *alone* are enough to be busted for an illegal machine gun if they are installed, and posession of same along with an AR might be construed as constructive posession. Not good. The BATFE will hand the rifle over to the technical guys, who know *exactly* how to make handloads that will follow fire two shots at least once in your "sample", and off to jail you go.

FWIW I searched all over atf.gov and could not find anything, however I did find a link to this very question on ar15.com.

You are correct on the handloads plus the selector switch can be manipulated in such a way to allow full-auto.
