I have a kwa with the new 2gx hop up and gearbox all stock, and im using an 11.1v 1300mah 20c lipo. When i shoot on semi its completely fine. But when i go full auto the bbs just drop after about 50ft. Is the gun just shooting to fast and the bbs colliding? I've over looked it plenty of times. Ive even tried systema bucking and madbull tightbore and still get the same results. So now im pretty much dumbfounded. Anyone have any ideas?? thnx
