Hi Guys,
I'm getting my Classic Army G3 next week, from wgcshop through ulaw(ASA). I need advice on upgrading it to 400fps-450fps Can the stock internals handle m120-m130 springs?

You will need to replace the your stock piston into aluminum, metal bushings and make sure that your shimming per gear is smooth. for it to work on the M130. With the M120 plastic piston is ok with good shimmings.
