Recently build a f2 Ak , gun shoots nozzle moves but it’s not feeding , I’ve tried 2 different mags and I’ve messed with loads of different fcu settings still no luck - could it be that I need a different sized nozzle for the ak im using ? It’s inside a CYMA gear box , using the nozzle that came with the f2 , in a what seems to be JG body ,
Gun has new barrel , new bucking and nub and they are installed correctly
