I went to an airsoft event last week and there was a guy there with a pistol that had a binary trigger (at least I think it was binary with the rate it was firing as full auto is banned) and a gas bottle kit attached, I'll go back and ask him what sort it is as I'm honestly not sure but it was an immense setup
I would say that either:
1) They used a mode against the rules
2) They are fast on the trigger
Bounce, multiple modes etc are/were prevalent in paintball
True ‘bounce’ is the physical or electronic double firing per trigger pull:
For example recoil, a worn sear or badly adjusted trigger/bolt system cause an occasional second shot
With micro switches etc a circuit could still have low power come through and be misinterpreted as another pull
Therefore you get a ‘debounce’ setting to fine tune how sensitive the circuit is for the next shot
When you restrict full auto, burst etc and the rate of fire of an electronically controlled trigger then when players are up against a semi auto mode or mechanical trigger then a player can pull their trigger as quickly as they like, and provided the bolt etc and next round is ready then a human being can pull the trigger more quickly than a restricted electronic mode
In my opinion binary triggers and bounce modes are worse than full auto or burst modes
In semi I have to keep pulling the trigger and everything stops when I stop
Even in an ‘assisted’ semi (ramping in paintball) I would need to achieve a physical rate of trigger pull, then as long as I keep pulling the trigger then a mode kicks in and fires at a preset maximum rate of fire
In burst then for example a burst if 3 shots are fired when the trigger is pulled
In full auto a constant rate of fire continues until the trigger is released
With a binary trigger you have lost control of your shooting:
Pull - it shoots
Release - it shoots again
I could fire one shot, then see something that makes me stop. I cannot release my finger without firing another shot
