Tom Gresham interviewed the designer some time ago (A year, maybe 2 ).
At that time he was battling the ATF who he had submitted an example to for approval, they broke it, then turned around and tried to charge him with manufacturing a "Machine gun". I have not heard anything about it since.
Bill, pay no attention to FQ, considering all the "Fire Storm" "Hellfire" and other trigger "actuators" on the market he is simply demonstrating his liberal lack of knowledge.
