Hey guys got this gun about a year ago and its about 280 FPS stock.
I'd like to upgrade it to about 400 FPS. I was thinking about upgrade it with a Systema Complete M120 Gearbox. I was wondering what you thought about them, or if there was a better route of going. Also would there be other upgrades I should do to it for that to work without trouble? I haven't upgraded a gun yet, so whatever you think would be the best bang for your buck would be the best advice please.
