CSS M4A1 Silenced Sounds for Tryhards

Name of this add-on already explains the purpose of the mod (or you just want to get rid of the annoying gun fire sounds, that's aight). Also no MP5 because it's a pain to work with.

Anyway, if you're having issues with the add-on, try snd_rebuildaudiocache or just simply replace the actual sound files on the game directory.

Forgot to mention this only replaces the sounds of Silenced MAC-10, Uzi, Military Sniper and Hunting Rifle.
