Halo 4 Specializations

Can I Get all the specializations (SP peeks and armors) with the common edition?
I know the ultimate edition (ultimate or something like that) have the access to all of the 8 SP, and I reed in a community that xbox gives a “present” for players of xbox live [of halo] (i think this happens since 2012). That “present” was a access to all SP.
But have some way i can unlock or earn this 6 other specializations?

i belive the specs were released to every1 ages ago its just certain people had early access via code or special editions

so i can’t unlock all the 6 Spec?

should be able to at 70ish?

im at SR now
