Yo surplus stacks without ruin wings! I told all my friends so they all grabbed one. Been doing this for such a long time. 4-5 rockets without wings. 6-7 with wings, so great. Also a great pvp sniper too with field scout and surplus. You get 12 from every crate I think and 6 shots per clip. I've had so many clutch kills with all those shots, even a 23 kill game last trials run. Just aim for the head!
