well. oops. already did it. i made sure that it cannot be made full auto by any means, so i wasnt exactly too worried about the thin gray line, as my intentions arent nefarious. but i couldnt stand the trigger on my kushnapup. im about 95% done as it stands now, just need to tweak the trigger, and mount a battery pack somewhere. if anyone is interested, i can post a picture or 2.

why not use an electronic trigger? a momentary switch behind your trigger, connected to a circuit controlling a solenoid, actuating the linkage inside the receiver. as long as the circuit is set up in such a way you cant fire more than once with each trigger pull, arent you technically still within ATF guidelines?
