There are already some m14 ebr for hunting rifle here on gamemaps. You can try to check these: M14 EBR (Hunting rifle) & CODOL MK14EBR Sky BLUE(Hunting Rifle) . You can also try to use search feature to search anything related to m14 ebr. As for port request, you can try to ask some people here who often do some port requests. You can find them when you browse "Mods" section.
