This is one of those weird "cross over" products between Real Steel and Airsoft. It's a DVD produced by a Japanese Airsoft Magazine of a bunch of real guns, being fired. Somehow they got time at some pretty cool places. Places like, HK-USA, HK Defense, Sigarms, Barrett, Iron Brigade Armory. It's pretty cool stuff if your a fan of either.
I just added links to the preview videos.
