    How much FPS is your KWA getting now? Upgrades aren't necessary for the FPS unless it's ridiculously low (250- FPS).

    I've heard all you need is a piston change, because the difference internally from the CQR and the other more expensive models is the I believe either the cylinder or the spring. Can't remember which. But read at one point on the KWA forums that upgrading the cylinder from the Type 0.5 to the type one will up the FPS. Also I remember something about stretching the oring a tad bit to I believe achieve better compression? The cylinder sounds like the way to go, the oring may also help out, but not 100% on that.

    You replace the cylinder to a kwa km4 cylinder, it should shoot 380-400 afterwards.
