Currently the gun shoots 550 fps with 0.2s (chronoed myself). I am using 0.3 bbs.. They drop after 60 feet, making the sniper pretty useless. I think maybe i broke or didnt put the hopup back correctly. Does anyone have a diagram or know anything about the hopup system? When i was clearing bbs out of the inner barrel, i took it off the system, and a gold piece fell out of the system. I just put that back where it fell out of, and inserted the inner barrel to the hopup when i put it all back togheter. Was there a certain way you had to put stuff back?
