the std ak is really awful! the gearbox is poorly made, need a new gearbox to replace the one in std ak v2. can v1 gearbox suit it? or other brand’s gearbox could do the substitute?
what seems to be the problem in it?
gears are missing in the gearbox
Now that’s different
not quite sure, but’s detached from gearbox anyway, a customer need a whole new gearbox as a replacement
