Looks like the ammo tray/belt is pretty exposed. Is this the way the operational unit is rigged?
You would have to be a pretty good shot to hit that ammo belt at 300 yards... especially with this thing barking at your forehead to the tune of 450 rounds a minute
Actually- somebody will correct me if I’m wrong, I think that the ammo belt moves through a protective metal duct, which is what we are seeing here. You could probably dump a bucket of mud over it and it would work fine, less any mud obscuring the video lens.
