DP-27

Nice. The Russia DP-27 is from Call Of Duty World At War. But I'm not yet try this LMG before.

M16 Commando

This assault rifle is okay. Actually it's the same from Call Of Duty Infinite Warfare. Here the url that looks the same. The M16 Commando you can put the Acog Scope, M203 Grenade Launcher and Holographic Sights. Nick, Louis, Rochelle Bill like to use assault rifle.
