The build I used for was Madness arms, 047AN05, and a single OGOTO. Max out Lock Speed and Radar Refresh. Get cover and pop up and shoot the snipers with the OGOTO until they are all dead, then use the madness arms on the NEXTs. Just don't miss. Dunno if you've been using the Madness Arms, but 2 hits pretty much kill everything... I found them fantastic against all the annoying, evasive bosses.
Hope this helps!
