So, I got my "Demon 3XB" MKII from loot box for 25th level of operation, but I didn't have this weapon before. The problem is that I'm not able to upgrade this weapon to unlock new attachments and camouflages for it. I tried to play various game mods and even reset the game, but nothing really helped. What am I supposed to do?
