Every other nozzle has a circular opening, while the prometheus is almost triangular. Why? Does anyone know if theres some reasoning behind this? Does it stabilize the bb better?

its still a circle, just with 3 smaller circles at 3 points. I dont know why, since it wont do any stabalizing since the hopup would fudge up anything the nozzel would do.

Very few nozzles have just circles for holes. Even stock TM ones have weird protrusions.

It's to prevent your piston, gears, motor and battery from getting totally borked.

The stock piston head is non-ventilated, right? We know how everything functions in the firing cycle of its phase. Air gets pushed out, yaddayaddayadda.

But when the piston is being pulled back, a non ventilated piston head will create a vaccuum inside the cylinder. A circular hole on a nozzle with a BB against it will create a seal for the vaccuum. If the pressure inside the cylinder builds up to high enough pressure, it will prevent the winding cycle of the firing sequence from occuring effectively or in a worst case scenario, completely stop the piston from moving - enough that the piston will work negatively against the gears and breaking something.

Over time, that added stress will get translated in to the motor and your battery as well.

Adding those three relief holes around the nozzle's exit will give a "suck back" ventilation path.

and there you have it
