Help with modding m16

Umm Im trying to mod the m16 into scorpion black. What m16/scorpion file do i use for the model? Ive tryed the ANI_G_SCORPION_CH and CM_HND_NM_DF_SCORPION_CH but the ANI made it just a crossmod with no texture and CM_HND_NM didnt work... For the m16 file im using the PVLMA File. What files should i use?? Im using Hex workshop
Btw.
