Um i suggest you to save money and just play on Escape mode or elimination cuz Escape mode will bring u many gp from your m16 and on elimination u can pick another weapon. Just save till sergeant and then buy berretta crates... If u have 25k gp more left u can buy 15 deagle crates and spin at the first black line and u will get it like i did. But if u wanna play safe, get 10k zp from ******s and spen on AWM RD, Minigun or Deagle scope crates and u will get gp from them. Then if u dont get AWM RD buy a normal one, if u dont get Deagle scope buy a normal one and if u dont get minigun buy a TAR21 or scar light
