It is noting like the HellFire device.

The key is the biased position of the trigger. Not allowing the trigger to move from a set position.

He used an SKS and MAC-90 in the above.

If you have an SKS you can do something similar. Squeeze the trigger lightly and slowly. Every once in a while you can get it to fire two or three rounds as his device does. That’s when the trigger is in his bias position. When you do it the recoil will quickly engage the sear so you can only get a couple of shots.
