I can't seem to attach any non Bis optics to any of the weapon packs except the mp5 pack. Any ideas why?:(

After Updating ASDG the Suppressors have indeed reappeared :D thanks for the help guys.

Don't know if this has been answered already it seems there are a few items missing from the ar15 pack for me. ar15/core are both up current versions I've uninstalled and reinstalled both with no luck all other packs work great. hlc_30rnd_556x45_S hlc_rifle_samr2 and Suppressors for 556 and .300
