I could see them going with an ar, shotty/sniper, and maybe a new special?
considering the peacekeeper is an AR/SMG hybrid and we already have (count them) 12 ARs already why would we need another exactly?
Not saying we need another, just going based off the lack of common sense treyarch seems to be using. And it doesn't matter whether the peacekeeper is an ar/smg hybrid, its going to fall under the smg category. So they could theoretically make an ar.
