great thanks mate il get in touch with them

nope, stock fps average using .20g bbs is 250, it uses the same gearbox and motor as the TM mac 10 and TM MP7. you think the spring may have been left compressed after being tested at the factory?

Hello, i recently bought a Jing Gong VZ61 AEP brand new and im already having problems with fps, on the box it says 250fps using 0.20g bb's, the closest i come to that is 180fps with .20g bb's, i have looked around the web and seen videos of people chronoing the exact same AEP and coming up with figures close to 250fps sometimes a little more from stock, any ideas of what the issue could be? (i managed to get 220fps but thats using 0.12g bb's) a loss of 70fps seems like a lot, cant get my head around what the issue could be!
