Upgrading basically works like this; first start with the barrel grouping for shot consistency. Hop-up chamber or unit, high quality barrel, get a proper R-hop mod and possibly a good nozzle. Later if you wish to increase power is when you may have to spend a lot more. Power comes from upgrading your spring and although power isn't the most defining factor it can open up the ability to use heavier rounds which can improve distance and stability. A bigger spring puts more tension on the whole gun and makes it harder to cycle. A gear and shim job will likely be necessary with the possibility of upgrading your gears and bushings. A stronger mechbox shell may then also be appropriate depending. All that extra cycling tension may now need a stronger motor to run it and in turn stronger batteries to power the motor.
Start with the barrel group and work backwards of you need to. A whole set of upgrades can run you several hundred dollars or more, so at the beginning just get what you need.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
