If I am correct, piston (Bottom) takes the small spring (On the right) in the cup portion, then the pin (Middle) goes into that. Large spring (Left) goes over the long part of the piston, then that goes into the reg housing, large spring, piston, with the pin sticking up. Place brass collar (Upper right) over this, and use the cap (Upper left) to screw everything into place and tighten it down.
Why do people do this wanna-be hk thing? I mean hk people dont even play paintball, they just whine and start drama while wearing the ugliest stuff. Seriously you find light blue and pink to be attractive colors for your parents 1500 dollar investment (your gun/marker)? If you want to whine keep it off the field and save it for the internet; O wait! THATS EXACTLY WHAT YOU DO! Haha, if you don't play then don't whine.
