It had been my favorite TR LMG until sound patch was done. Other things are fine. MSW-R now feels like a real machinegun. CARV has great gunfire as well but I think old TMG-50's fire sound was better.
New sound is awesome, if you like your heaviest hitting LMG to sound like a wet noodle dropping on the floor. Old sound one had bass to it and made the weapon "feel" like the heaviest hitting TR LMG. That being said, just release a "sound attachment slot" for weapons already and let us use what we want, because in the end its all about personal taste. (While making some extra $$ aswell. SOE you know you want to. You cant resist. Its almost free money.)
