While that is undoubteldy a fine Rifleman, I think it's underammoed (it need moar precision), and it needs higher damage weapons.
I would try to fit a Gauss and AES or TC in there. 15 damage can core some light mechs if you hit the back, and at least penetrate the front. -1 is just mandatory to get a hit.
Plus, LRMs with SG aren't bad either.
It gets the job done
