What to get to upgrade my gun to roughly 425 fps?

[The dude 123]

Ok i am open to anyone with suggestions, i was looking over the spring chart (nice job illusion thanks for taking the time to do that) and i was reading the first page of this post and I am just wondering if anyone can give me some ideas on what to get to upgrade my gun to roughly 425 fps, i am takeing into consideration the few extra fps with the barrels and stuff here and there.

Im looking into a new barrel and spring bushings and anything else i may need for my ca m15a4, it is all stock at the momment.

thanks so much for your advice you may e-mail me if you like my e-mail is: rbs112@swbell.net

thanks again,
The dude

upgrade all your gears and possibly the moter and piston. Replace the mechbox with a high strength. I dont really know what your talking about for the barrel, theres no real need to chenge that out, just internals.

start bringing a few more batterys out into the field aswell. My C7 is shooting just under 400 and its frigin SWEET. My next plan is the boar up kit for the cylinder to puch more air out with every bb.

Hope this helps a but.

Just use the upgrade suggestions in the stickied subjects at the top of this part of the forums.
400 is the general upper limit here, so please update your personal profile with your location (if you are not in Canada).

Otherwise, I would not touch it until it breaks.
