A build I stumbled upon while tinkering in the mechlab. This turned out to be surprisingly effective, though. cUAC5s and cERPPC nearly share the same projectile speed (1200 m/s vs. 1150 m/s), so sniping will result in quite a lot of pinpoint damage with the added bonus of cockpit shake. To add to this effect I recommend using two different weapon groups for the UACs - one for group fire, one for chain fire. Poptarting is possible as well in this build, but not very recommended.
