Add the weaponfiles and sounds into your mod.csv.
Btw you don't need to add the sounds into your mods folder. They will be automaticly added from your mod.csv.
And you can use Bam's Perks, if you would like an easy version of the BO perks. If you need help with them just ask :)
in mod.csv, when you comment stuff out, remember to add a space, or the line after is ignored too
