Very fun... Closed bolt sub-machine gun that some will argue is the evolution of the MP5 series... Can be chambered in 9mm, 40 S&W, and 45 ACP.. I believe there may be a 10mm variant floating around somewhere as well.. I wear glasses normally but the range policy was safety glasses over regular glasses so as you can tell they did not fit snug
