It’s clearly not airsoft and it’s clearly a civilian M16A2 clone. The rear sight tells us it’s A2 or newer, the fact that the carrying handle is fixed to the upper reciever tells us it’s not an A3 or A4. The long barrel without flash hider and the lack of a bayonet lug tells us it’s a civilian version, probably semi auto. The magnifying scope sitting on the rear part of the bi-level rail looks like an american copy of a Schmidt & Bender scope and in front of it sits an Aimpoint Comp M2 (or ML2) on a cantilever mount. The magazine is a Beta-C 100 round magazine, above that we see a brass catcher bag. Under the rail, around the front carrying handle there is sling mount velcroed on. Under the front handguard there is some sort of vertical grip with a rail under it; either a tri-rail or a straight rail with a tri-rail adapter under it. On that there sits two flashlights I can’t place the exact make of on the left side and under it. On the right side sits some kind of civilan clone of a PAQ4 or other LAM with a flashlight on it also.
