Fully Upgraded MTW Billet Gen 3 with added Daniel Defense Furniture, Magpul Pistol Grip, Maxx Hop Up Chamber, Upgraded Bucking, Tight Bore Barrel, Mock Suppressor, Daniel Defense Foregrip, & Real Steel Charging Handle! The replica has been used at a few open play games but is almost brand new and works amazingly. I am willing to negotiate on the price of this
