I know there are a lot of gspec owners on here and i found a good mod if you have already upgraded the piston is take the o ring of the stock piston and put it on the aftermarket one. i got a huge difference in compression and yest my gun is shooting harder now. i know a lot of you know this but just a quick tip for those who do not

thanks for the tip dev, but also, if you happen to have lost or thrown away the stock o-ring, a #13 (7/8" OD x 11/16" ID x 3/32") o-ring from home depot is the perfect size

yup theres about 5-10 rings in the box that you can get at home depot
