This was spotted in Crimea recently, that doesn’t look very Russian to me. From what I can tell he’s using an Adams Arms Piston upper, Zeiss scope, Magpul butt-stock and angled foregrip and a Primary Weapons Systems KAC556 muzzle brake. Pity about the barrel mounted bipod, it’s actually a pretty nice build minus that.
It is a nice weapon system very useful for the army for good result in their operation.
