I had a reflex and a silenced but I found myself only using it silenced, i just like the feel of it. I used Hi cap mags so I could actually get 2 people without reloading, but switched to RTM, Heavy Hitter, I use on everything I don't use light foot on, I don't personally care for armor but if you like it more use it, and BB because its the best gadget in that class, that doesn't mak it a good gadget
In a Nutshell
Play a bit more conservative if possible (don't camp) but you can rush with this.
And always reload cancel (Sprint after loading the mag)
