One thing that is missing, you really don't need fps for amazing range. First thing you should do, no matter what, is upgrade the hop system. The r-hop by HS5 is very effective, and the LRB system employed by classic airsoft is also very effective. The r-hop is slightly easier to apply in an AEG platform, and as such, I would highly recommend, if you don't have the tools to do it yourself, buy a Prommy steel barrel and pay HS5 or Skag187 to install an ER-hop for you. Then, work on power upgrades, if you still think you need them. However, with a nice hop system you should get some nice range without needing to upgrade the power too much.
