New CS:GO AK-47/AUG/M4A4/A1-S/FAMAS/SG 553/Galil AR sounds

As included in the 9/28/16 (9/29/16 UTC) update: Original sounds are also a bit ear-rapey, so I’ve nudged the DB down to a point where you can still make out all details but without destroying your eardrums. file paths included for those that want to get at the files themselves for their own purposes.
