So after playing around with a long time on an Annihilator 2A build, swapping around autocannons to pair up with RAC2's etc., looking at heat, DPS, etc., I thought again of my FNR-5 Quad Light Gauss Stealth build. Light Gauss rifles are heavy, and doing 4 Light Gauss with stealth practically makes you a meme (although BackdoorShotgun is pretty good with his). I started wondering about how the heat of 4 AC5's would creep up with stealth armor engaged, and came up with this. The AC5's are very cool-running. I'm going to take this into the wild for testing, but I've been able to DPS-kill all 8 training ground mechs with Stealth Mode on without heat problems. Seems to be a good build. Faster than the other stealth build, quicker to respond, easier to store ammo, and more armor. The only disadvantage I see with this (over quad LG) is slower projectile velocity and visible dakka.
