Farm either Nike's Rampage, or... uh, not sure about which one it is. Monster Prognostication maybe?

Both of those maps have 8 mobs (sadly no 9 mobs anywhere), but the latter (if I have the right name, not sure) occasionally spawns a Rare mob. A Rare mob means slightly less mats, but should drop you a R weapon every time.
