Not enough ammo for QP, strictly an attempt to break the Division 1 meta. Came up with the concept at work so I haven't been able to test it yet, will do so next time I'm online. If anyone tries this, feel free to leave feedback!
Alternatively, you can run a single RAC5 and add 5xERML instead, Or no ERMLs and a STD240, but that's negligible in speed increase.
