The yellow pod is a FLIR of some sort, probably a prototype since it's not painted to match. I don't think it's a photo-chop since the color does reflect off the lower pod, there aren't any harsh cut-paste lines around it, and that god-awful bracket is just the sort of thing we'd rig up during my days at Grumman. That lower pod just looks to be your standard, run of the mill, "reach out and ruin someone's day" rifle. Probably isn't particularly effective against a person at range, but plenty accurate enough for shots against light vehicles.
