I purchased my first airsoft rifle around June. It was the G&G CM16 Raider L. It works fine except the hop up doesn't really change anything about the BB flight trajectory. It literally stays the same no matter how I change it. It doesn't go up at all, all it does is dip after about 20 feet. The FPS is around 375 with .20g bbs. Does anyone know if there's a fix for this? If I decided to get a different hop up, would I have to upgrade anything else to compensate for the hop up upgrade? Thanks!
