full auto bcg's are ok, but i doubt a trigger system would be and i wouldn't want to be a test case....
but the gun can sometimes be made to fire full auto without the sear using ALL of the other M16 parts and soft primer ammo. If it fires more than once, you have a machinegun. .
the only difference is a hook on the hammer and a slot at the back of the trigger. tens of thousands of these were sold in fcg kits during the 70's-80's.
they were cheaper and the ATF wasn't so uppity. there is no difference in their operation than the semi-auto trigger and hammer. you also have to remember the ATF changes its mind constantly and it wasn't that long ago you couldn't have a m16 bolt carrier in your gun.
How does this work nighthawk? Are they pre-86? Or just replacement parts for existing? I never realized you could still buy these even with a stamp.

Nothing screams poor craftsmanship like wrinkles in your duct tape
But doesnt the lower receiver have to have an extra hole in it for the third stage sear? If a semi auto lower did not have it could they charge intent?
