Help with custom sweps

Hi everyone. i’m new to this thread so I apologise if i’m doing anything wrong. i’ve been trying to work out how to get all the sounds working from custom skins from fps banana. i’ve downloaded a high quality m4 skin, hexed the models, but i cant get the sounds working, only the firing sounds.
Note: i’m using mad cow’s weapons base for my personal use and NOT uploading it as my own work

any help for the sounds would be greatly appreciated.

It’s ok. I worked out i have to hex the sound paths too.
