Discard the left arm for a C-UAC20 'hidden' in the RT. C-LRMs are fine for brawling (which is their intended purpose), just make sure you stay in the 180-360m sweet spot. Rattle your enemies to death with repeated 4 damage slugs and streams of 1 damage missiles. ERMLs to finish people off with precision, and long range poke.
I really have much fun with this. Had to meddle with it a bit to suit my playstyle but this is my favorite config so far. I moved the LRM to the left arm because it turned me into the hunchback's cousin and removed a bit LRM ammo for armour. I use my lasers and the LRM to soften targets and then move in for the kill with the UAC. If you want to sacrifice some flexibility for being able to really ruin people's days quickly, you might try this
