Interesting indeed. If you go by the commonly accepted definitions appears to still be semi-automatic function. 1 tripper pull = 1 round fired.
Anyone remember Hellfire triggers? I had a friend that had one of these on a Thompson replica. Looks similar. Getting it to work was tough though.
Why not?I wouldn't buy one unless there is a letter from the ATF saying they are legal.
I had a binary trigger on my AR. Bolt kept outrunning the trigger and could never get more than 5 or 6 rounds off without a jam. Sold it.
