You can definitely upgrade it considerably, but it still probably will not be as good as an A5. The cyclone feed is a great idea and works really well to prevent chops. How often do you break paint in your AB? What kind of loader are you using? CO2 or HPA?
I just got a gravity loader (cheapest) And i'm using Co2. I have shoot like 2500 pballs and have chop none. But i can still buy a cyclone for the AB. What do you think?
