Just out of curiosity, how do they down-convert these rifles from fully automatic to semi automatic in your part of the world?

I can see a stud welded on the receiver in your photos that prevents the fire control lever from moving past Einzelfeuer (single fire) to Mitrailleuse (Rapid Fire). Is this the limit to the modifications to the gun much like the Britishicon did with the SLR, or have they also deprecated the auto-sear and other elements of the fire control group?

It's interesting the way that in the US we can't have any down converted full auto guns, the receivers would have to be chopped up for import.
