Found this one, too. Did you find out, what it is for? So far, i was not able to attach it to any gun.Are you sure its a bug? I think there is such a muzzle item wich is not a suppressor that does not seem to have any stats in the description. I never tried but perhaps thats for LMG´s?
same here, also raise the DPS ...there are pistols and SMG and Rifles that do more damage ,that's pretty sad for a LMG.At the moment, LMG Defender is bugged and you can't install more than one modification on it. This is the only machine gun in the game and it is faulty.
