This video shows off the AK-15. The same rifle as the AK-12, but in 7.62×39. One notable change in the AK-12 and AK-15 over the venerable AK-47/AKM/AK74 is a free floating barrel with the gas tube fixed to the receiver. It also has a side folding collapsing butt stock.
But the most interesting thing about this video is over at 27 seconds the target they show appears to show key-holing. This is where the bullet impacts the target sideways. Not very impressive from any rifle.
