Alright, so I recently bought a JG G36c as an upgrade gun. I got it for 90$ish brand new What I want out of it is a some what realistic set-up. I want 17-18 RPS, good trigger response, accuracy, and range at around 365FPS. I have a budget, but at this time it's about 150$-200$, it could raise or lower. I will be ordering all of the parts I can from either EhobbyAsia or WGC Shop. My current parts list: Gears: stock JG gears. (unless it won't work, I would think it would though.) Spring: SHS M110. Bearings: SHS 7mm steel bearings. (I tried to put 7mm CA steel bushing into it and they didn't fit..... I had them laying around and thought I'd try.) Piston: SHS Piston full metal rack. Piston Head: Lonex Aluminum Piston Head with bearings. Spring Guide: already replaced with a modify spring guide with bearings, that I had laying around. Motor: Lonex A2. Barrel: Prometheus 6.03mm. (will be stabilized) Hop-up: Systema bucking and a Lonex soft bucking. (will be fine tuned) Airnozzle: Lonex. Shims: G&P shims. (already done) Tappet Plate: using stock one. (unless someone disagrees for a good reason) Wiring: 16 awg wiring. Deans. Not sure if I need anything else. Battery: I was thinking a 7.4 Lipo (not sure what C rating) so I don't have to install a MOSFET. I have already done all of the AOE, shimming, regrease/lube, and I couldn't get the compression perfect with the stcok airnozzle so, that's why a new one's on my list. If you have something to add, please do. As I am not as experienced as some of you. Constructive criticism is appreciated! EDIT: Also, sometimes when I switch to semi it doesn't shoot. It just makes a "click" noise whenever I pull the trigger. I think I know what's wrong with it, but I figured I should ask before I do.
