Ever since the Trump Administration moved to ban bump stocks many gun owners were left in the dark as to what else was going to be included within the ruling. Those with binary or aftermarket triggers were now in the the cross-hairs of the ban. The Gun Collectives’s Adam Kraut covered the bump-stock ban in detail and it seems that Binary Triggers have dodged a bullet According to the DOJ.
In regards to the Binary triggers the DOJ states that Binary triggers will not be reclassified as machine guns as a single function of the trigger includes single pull of the trigger. So the single pull of the binary fires one round and that counts as only one function. The firing of a round upon the release of the trigger is the result of a separate function of the trigger. Therefore they do not meet the ATFs phrasing.
You can view Page 83 of the final ruling below:
In short the ATF claims that a bump stocks unique and distinctive operation allows the firing of multiple rounds after the initial function of the trigger through recoil energy bypassing further manipulation of the trigger while the binary triggers sequence is technically two separate functions of the trigger and thus not a machinegun.
