The Ares Airsoft version of the H&K UMP is given a quick review by Daniel of Airsoft GI... "Many players start their airsoft career in an indoor field or some sort of CQB environment. If you are looking for a gun that is perfect for cutting corners, look no further than the H&K UMP. With an included high capacity magazine with fake rounds and the blowback feature on the gun, this gun in the right hands can do some work! Be sure to check it out on our website!"
