Can anyone help me to get custom replace gun sounds (client-side). I have tried many different thing but non of them works.

Especially result 2 as it is the most complete example of .awc based resources in their current state. The only thing that can’t be done (if I recall correctly) is single channel audio files, but things such as weapon & radio station audio will work as expected.
