I use the R3F weapon-mod and the "heavy" sniper rifles, like the PGM Hecate, are using both, rifle AND launcher slot and this is pretty annoying...

You know that the GR armory was a pre-mission armory? So youre still unable to switch weapon parts in the fight. So it has the same efect like a BiS pre-defined gun. Even the good old Rainbow Six Vegas 2 was better than GR in this way because you could (dis)mount a silencer while playing...

It's so stupid... Sometimes you have to observe and make sure that your target is a enemy. Don't shoot at everything which moves!
