I see that I have UNLOCKED some guns...as I look I see them and it say "UNLOCKED", but how do I equip them? If I go to my load-out screen for equipping guns etc. I don't see them there and when I go to the tab that says "more" or "see more", it just takes me back to where the UNLOCKED guns are, yet....still don't know how to equip them. Please help?
