Real steel review by The Firearm Blog TV covers the Angstadt Arms MDP-9 Carbine... "In this episode of TFBTV, James Reeves is at Thunder Ranch to test the new Angstadt MDP-9. The MDP-9 is a bit like an H&K MP5 crossed with an AR-15: it uses the soft, roller-delayed blowback system of the MP5 and a tri-lug mounting system, but all of the controls and even many of the parts of the AR-9 and AR-15. However, at $2,700, this could be a tough sell. Is it worth it? Check out this review and tell us what you think."
