quote: I also believe that the POS perp in this case did not have Full Auto
weapons, it sounded like he likely had a bump-fire stock or maybe
one of the newer Binary Triggers, once I heard audio of the attacks.
The Full Auto is a constant rate of fire, but the 2 things I listed have
a variable rate of fire due to the user input...
I posted that yesterday, but I heard the audio Monday on the Dana Loesch show.
The amount of pressure forward on the handguard determines actual rate of fire,
and the cowardly perp was adjusting his grip in the audio clip I heard, which
altered the rate of fire. Less pressure can result in a higher rate, but too little
will stop the reciprocation of the receiver, which interrupts the trigger pulls.
So will too much pressure forward, it stops the movement.
Pic of a "bump-fire stock" as installed on an AR-15:
This is the original SLIDEFIRE Stock, and a company later brought a cheaper version to market called Bumpfire,
the name being descriptive of the process where the gun is allowed to rock back and forth to simulate Full Auto firing rates. It can be done with a thumb hooked through a belt loop and the recoil causes the gun to reciprocate and the stationary thumb repeatedly engages the trigger, similar to the stocks. All of these are 100% legal to use, buy and transfer.
