Upgraded KWA G19, lost 60FPS
I just recently upgraded my G19 with a PGC slide, PGC hi flow valve, Shooter's Design rocket valve, and PDI 6.01mm tightbore barrel. I was hoping to be at least around 350FPS since it was 330 stock, and when I tested it today I was lucky to break 270FPS. The temperature is the same as when I tested it before, so what could it be? Maybe something is messed up with the hop-up, I did have some trouble remembering how to put it back together, but I know it's right now.
Any ideas?
