1. Have a friend pick smg3 and weapon silencer 2. Stand by friend 3. Have friend fire 4. No sound happens for you. Reznov says it's barely audible for the shooter.
I think in the description it says it only lowers volume of shots by 50%. There's a difference between 50% and 100%.
@Candles: Really? I thought silenced weapons atleast make a slight noise, even if it is silenced. I imagined something like 80-90% of its original world_sound effect.
