I've started running a Thesan with Hot Swap, Skip Rounds, and Rangefinder. I have yet to get a sick rebound kill, but I'm enjoying it. Edit: Forgot to mention that it's a massive upgrade from my old FR. I used to run a Midha's Reckoning. Not a Harrowed one. A normal one. My strategy was to point it straight at their feet and pray to God that the recoil would launch the bullets into their face.
