[edit]
The XM8 M320 is a 5.56 mm assault rifle used exclusively by ION private military contractors in ArmA 2. It was added with the release of the Private Military Company DLC.
Overview
The XM8 M320 is a modified variant of the baseline XM8 rifle that has had an underbarrel grenade launcher attached to it.
It is completely identical statistics-wise, and can load either the standard 30 round STANAGs or G36-type plastic magazines like its parent weapon. It is however, slightly heavier to carry due to the added weight of the M320 grenade launcher.
The M320 uses a conventional flip-up leaf sight and can launch 40 mm high-explosive (HE), flare, and smoke grenades at distances of up to 300 metres.
