[jimwu]

Hi All ! Need to ask one question here , today I receive my g&p gearbox , but after I trial fit it to the chamber and feel lose is it ok , mean the nozzle size a bit smaller than the chamber hole .
Hope u all know what I mean

cheers

Is ok now , I know what is happen and I did some mod then everything is back to normal , and there is one more thing I wanted to know is what is the function of the charge handle ?
And what and how to use the chamber gear ?
tks

cheers

charging handle does nothing
chamber gear I'm guessing is your hopup dial
shoot a BB, if it goes down, adjust the dial clockwise to get more hop up
if the BB flies upwards, adjust the dial the other way to reduce hop up
