How to change weapon skins on Halo 4?

I got the arctic camo for the BR that came with a pre-order of Halo 4, and it disappeared today. I’m thinking I changed the skin by mistake, but I can’t anywhere to do that. Can anyone help me out?

The skin is actually another BR choice in your primary weapon slot in your loadout.
BR ARTC I think.

EDIT: @#$% This was a necro’d thread.

Look in your loadout creation for BR Artic. I await your response OP.

Sometimes a glitch occurs where a skin or Specalisation doesn’t show. Reboot from the 360 or game and it should resolve.
