Just bought one of these used and I'm wondering about what others have done to improve the performance of this nice marker. Currently it has an upgraded barrel, Venturi bolt and expansion chamber. Any other mods anyone can recommend would be great.

great gun barrel should be all you need.

you know what kind of threads are on it? I got a barrel with it but if I'm going to get another one I need to know what to look for.

Same threads as an A5

In the old days of CO2 only. An expansion chamber was needed to reduce the amount of liquid co2 going into the gun. So if planning to use co2 should probably have one on it. Will work with HPA in which cause the expansion chamber is not needed.
