Nvm everything works, I didn't realize there was another launcher to enable mods.
Nope, that would explain why they aren't applying in game. Can you give me a link? And if you mean the vanilla Arma 3 launcher (the one that comes directly with the game) then yes I'm using that.

Maybe even adding a sling function so you can switch to your side arm even faster?
