I'm not sure if you understand how the marker works...
The ram/bolt combo as well as turning a reg down MAY help, but the problem isn't the ram and bolt when you drop the pressure as much as the valve returning enough pressure to force the ram and bolt back against the spring's pressure. Turning the pressure down directly affects the marker's ability to cycle, and with the balancing act that is a blowback you do NOT want that. With a Blitz you're balanced between a high pressure, ram momentum, and strong ram spring, turn the pressure down too much and the gun won't cycle, turn it up too high and the gun also might not cycle if the valve is held shut by the air pressure behind it and even if it does fire it'll be shooting velocities too high to play.
What the Zero system does is it reduces the pressure and increases the volume allowing the same amount of air in except at a lower pressure, so you still have enough pressure to fire the gun AND propel the ram back to catch on the sear.
High pressure + low volume = Happy player
Low pressure + low volume = Unhappy player
High pressure + high volume = Player not allowed to play
Low pressure + high volume = Happy player with a somewhat quieter gun
