Hey guys I'm going to be getting some money for my birthday on November 30 and I would like to spend it on getting upgrades for my gun. All work will be done at my local airsoft store No Limit Airsoft because they do it for a pretty good price and they do a good job. I'd like to keep it under $60 if possible but I can go up to $90. I want to make a mid-range semi high-speed build. I'm going to be running it on a 9.9 volt 40c 1800 mah LiFe battery and the gun will be my JG M4. I already have a new hop-up bucking because the stock one tore and the one I got is the element 55' bucking. Here's the parts list of things I want to get : shs 13:1 high speed gears, correct AOE, reshim, and get the new hop-up put in. Any reccomendations on other must have things that won't cost me too much? And what kind of rof would I get with this setup? I'm thinking mid 40s but I could be wrong. How many rounds do you see this thing going through before something breaks? Help from experienced techs is greatly appreciated.
