Re: M2 carbines
300 Any machinegun is controllable, If you shoot it right. Just because you can shoot full-auto don't mean you have to shoot it full auto, Just shoot some nice controllable burst, I have shot a Glock 18 and it is completly controlable if you shoot 3-5 round burst but in full auto it is like trying to hold on to a fire house with one hand.
But the above statement don't apply on Mac's and other open bolt machinegun because if you let go of the trigger and the bolt is closed it will not shoot again with out cocking it again
Only you can see this
