I have a theory about this. Polishing internals has generally shown an increase in velocity due to a lower amount of friction of the internals. People tend to do this for better efficiency and consistency. That means that more energy is moving the hammer forward instead of being dissipated through friction, which moves the hammer faster and consequently hits the valve harder. That means that more volume of air is being expelled and results in a higher velocity for users. In other words, polishing internals gives a similar result to putting in a stiffer drive spring.

Now for people using a regulator, that means they can turn down their pressure to help save on the air.

Now for those without a regulator, that means they need to turn their FVA in more to cause more air turbulence to slow the ball down. However, they're still expelling more air than before and can't control the rate unless they can find a weaker than stock drive spring (does one even exist?) to replace it.

So does that mean for people with guns without a regulator or weaker spring (aka mostly stock), they're actually getting WORSE air efficiency?

Please discuss.
