RE: AR15 Belt Fed 9mm Tigershark Billet aluminum receiver
That is SO SICK! It's actually little metal links and the way the belt fits in that bag is awesome, It's way cooler than I even thought and the shark lower is awesome! Thanks for sharing that! The forend looks sweet too I'm guessing it's got a heat shield in there for shooting 1000 rounds at a pop?! What length barrel does it have?
