The way rifles work with recoils driving the expulsion of a shell after firing and using that force to load the next round to chamber (the famous AK47 design)

Would there be a method of attaching a compressed water bottle with valve with a donut nozzle with vents out at angles to the optimal suppression of the muzzle flash.
The idea being that, like a paintball gun, the machine's trigger pull, also has a tangential trig that pulls an outburst a micro second from the rifle, in a ring mist of water/(some more expensive, toxic military fire-suppressant (ironic) to reduce the muzzle flash on shot...
May it reduce the muzzle flare? or is it too weak? Should it launch behind muzzle, after muzzle?
The bullet down the barrel triggers the valve when it hits 50% of barrel length. Once that induction occurs, it triggers the valve, and the flame suppressant cloud is spit out micro seconds prior to bullet breach...

I am convinced that we can use Davincis micro fluidics... turbulence drawings.

So let talk about next gen firing
The barrel release could be routed to drive the exhaust through channels which drive micro-turbine motors that slurp back through the external of barrel and infuse with water.
Working on this in Solid
