Pack-fed PKM machine gun hotness (VIDEO)

Oh, I want one of these so bad now. I need one, I can feel it in my tactical dump bags.

Apparently, some shifty Ukrainians have rigged up a prototype backpack feed system, kinda like the Ironman, to work with the PKM LMG. I’d take one today, kinks and all. When they get this working smoothly…

I think it may work better with a sideways feed out of the pack, and obviously it’s gonna get a better machine gun mount at the feed tray — how would you tweak this to make it work better?
