I purchased the G&G Full Metal GC-16 a month or so ago from Evike. It came to me pretty loose; buffer tube, rails, outer barrel front section fell off. I got everything nice and tight now though. After stripping the spring guide, I replaced it with a Lonex ball bearing type. So I've been in the gear box and feel comfortable working on the thing. I've also upgraded to Deans. I took it out last weekend and it did good. I defiantly want better trigger response and maybe a small bump in the ROF, my chrono says 13.5rps currently; I wouldn't mind low twenty's. I ordered a Lonex metal hop up I'm going to pair with a G&G green bucking and flat hop. I also ordered a SHS high torque motor, I know at 16TPA people say it's not really high torque. I'm hoping it will help with my trigger response and rate of fire a bit over the stock motor. Ive been reading a lot about the G&Gs doing fine stock but having problems with internals once you start upgrading them. Have I started down a road of pain by getting this motor? Should I just start ordering upgraded internals now? I'm probably going to keep the stock spring as it currently gets around 345-349fps with .20s and 299-305fps with .25s, I still want to meet regs at the field. I plan on AOE correction and have been looking at the Gate Titan, I'm so close to hitting the buy button on that it's not funny. I'm also thinking about the Prometheus EG Tight Bore to pair with the Lonex hopup. My goal is to turn this thing into a super reliable, responsive, accurate beast. I want to get into mill sim so crazy ROF and super high FPS is probably not something I'm shooting for, yup I said that. Any suggestions from more experienced airsofters to help me reach my goals with this gun would be appreciated.
