[WolvesSoulZ]

A freshly upgraded Cyma cm028 with:
Guarder 6.02mm TB barrel
Madbull Shark Accellerator Hop up + Fishbone spacer
TM eg1000 motor
Guarder sp120 spring
(FTK-27)

Pretty much what I'm running atm.

Edit: Also, when I tried to shoot a cola can, it didn't alway go through it, but the battery seemed to be low in power, with the spring it's supposed to have 380-410fps if I remember well.
(Guarder suggests customer to use 9.6V 1700mAh or higher battery for best result.)
