Hercules Gear share what they think about the Japan version of the licensed Umarex/GHK Glock 17 GEN5 MOS Cerakote GBB that many are anticipating... "We would like to introduce the latest model of the popular GHK gas blowback handgun. Officially licensed by GLOCK, it is life-size! Engraving! Cerakote! Every detail is reproduced realistically, and it is a special gun that combines an internal mechanism that allows you to experience a strong blowback! We also disassembled it and compared it with the previous model GLOCK17GEN3."
