I just just recently got my hands on the Ak-74u Sd. It is a great gun regardless, but I have came upon a problem. It you turn the light on for the gun and then reload manually the light turns off. The light helps me in spar, but reloading then having turn the light on give the opponent a chance to get you a good 1-3 times. I have no idea if this is a bug or meant to be. I hope that this idea gets implemented / bug gets fixed.
