The New CRAZY system makes is difference by having in the barrel end an external chamber that move part of the propeller gas (or air compressed) around the bb bullet, creating just ot of the barrel a trajectory protection to avoid external agent to disturb bb fly.
the effect is more accurate with gas or co2 pistols that maintain the propellent pressure even in open air
