K-volt is a great weapon. I started using it recently to get the Elite assessment for it. I use NR, RF and CO to it and I only just clicking it like hell. I realised that the pellets are slow, so firing it continuesly is non-sense, you will miss the most of your shots if a person is moving from left to right in front of you. Shooting continuesly is only good with hipfire, while danger close to your enemy.
I personally casted a vote on the Grendel, it's my fav weapon currently, but if there would be a second option I would mark scarab as second. And Andrey, scarab won't make you noob, non of the weapons makes no one a noob, so don't worry.
