You can use CE to manualy set it value to 13 but onestly is useless and look orrible 'cuz all part of the gun will gold and if you use ghilli suite or other to hide yourself gold will only advantage enemy. I prefer brown leather camo, anyway i raccomand "cod ghosts AJ pack" CE table is the most complete and easy to use
P.S. used gold only for 2 match and if you use poor quality gpu, have very ugly look, my dedi videocard is gtx780 Ghz Edition and dont cap more then 50% with ghosts
