Why not make it all semi-auto, I mean for all SF rifle.
I don’t think a soldier would set his full power cartridge battle rifle to full auto most of the time.
I think about this issue from a whole different perspective… in a combat situation its less forgiving if you shoot your enemy in full auto while expecting semi auto fire,
while anticipating full auto but shooting only once will get you killed - that’s why I think EVERY weapon should always start in full auto.
