"this cylinder set is awesome. i put it on my ics cxp 16 sport line and my fps whent from 358 to 410 with an m 100 spring and a MAPLE LEAF BUCKING. i didn't use the nozzle because it doesn't fit in my ics hop up up unit but I tested the compression any way, I wasn't impressed probably because the o ring isn't thick enough to get 100% seal.

"This is by far the best kit in the market, the cylinder head and piston head gave perfect compression, no air leaking at all. However the nozzle that came with the kit seems to be a bore up nozzle (high-flow) might be shorter than standard m4 nozzles.
