They (genuine full-auto lowers) are different on the inside (3rd pin-hole & the shelf), but will not allow full-auto by itself.

Select-fire receivers are regulated by the ATF/NFA, and are not eligible for export from the U.S. (same as .50BMG) IIRC.
A lil' confirmation from Questar may be in order...

I asked the guys at Spike's tactical, and they said the 3 position receivers are just "dummy" markings for select fire. I don't see why they couldnt be imported, but I'm sure there is a silly reason why they arent here.
