Re: M4 no full auto?

selector plate is stuck or selector switch is not tight on the rear or the cam is too tight inside the gearbox any of these will cause this problem best solution speak to any of the gun guru's at zero one

Just for the recod, this'll be a loose or worn doen fire selecter or selector switch.

What's happening is, the selector switch isn't quite being moved far enough to engage full auto. What you get instead is the cut off lever blocking the trigger contacts, as oppose to it being above them as it should be when full is enagaged.
