You fail to understand the finer points of a binary trigger. They make controlled pairs ridiculously easy. You'd have to go through ammunition like Jerry Miculek to train to be be able to get two holes that close together with a conventional trigger.
Those are Lightning Links, now classified as NFA devices. There are still some transferrable ones out there but they've now all been serialized and taxed by an ATF Form 1.
That was all it took, provided you had an older Colt SP1 lower and the time to tinker with the timing, to make an AR-15 rock-n-roll.
