Newly Ares UMP at Gunner Airsoft. This one is, we think, an improvement over the Star UMP and this comes with 110-round magazine. You can purchase a 460-round magazine separately which is not yet available at Gunner Airsoft. This has a folding stock, metal gearbox, and the rear sight is the same as a TM-G36C. Battery installation is a breeze via the rear area. This costs US$185 which is not a bad price after all.
