Pretty basic concept, surprised no one's posted this one yet. I realize Inner Sphere UAC20s aren't super popular, but if you like boating 'em, this is a good 'Mech to run it on. Swap for Standard MLs if you prefer, but they're really just for closing and as backup weaponry when the UACs jam. I wouldn't recommend firing them really AT ALL once you've engaged with your UACs, as the heat from them alone is considerable.
