gear box air nozzle
 

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

Is it need to be adjust all the time or only once ??
tks

needs to be adjusted whenever you need it to be adjusted

Oh ok tks again :)
