Me personally it would have to be the M4OA3, purely for nostalgia reasons really, I feel they got snipers right in this game, so would be nice to see this beut on the battlefield. --- Sometimes when I close my eyes, I can't see.
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.
