Hi guys I need some help. I recently purchased B3YOND bundle specifically for KAR98K. I had the gun unlocked initially through Armory but because it was not levelling up, I went for this bundle. Now the game tells me that this blueprint includes locked attachments and some attachments are not available to use in warzone? Can someone please guide me on this. Also, what is the best way to level up this gun and permanently unlock all the attachments? I do own Modern Warfare 3, Modern Warfare 2, Black OPS 6, and Black OPS 7.
