I didnt Recieve Mark VI armor and scarred in Halo5

Hi, I didnt have MCC on my xbox but I let my friend go on my account and unlock the achievement for me to get the armor and he told me he finish it and got the achievement. So I went on Halo 5 and check to see its unlock and I still didnt get it yet. Is there anything im missing or unless I need MCC install.

I am having problems as well with the Mark VI… So can you tell me how you got it please

i have the gen 1 mark VI but not the scarred during the last update but i still havent recieved the other armor…and i unlocked the achievement a couple of months ago… i hope 343 is trying to fix the issue
