Umarex Glock GBB G17 Gen5 MOS
The Umarex Glock GBB G17 Gen5 MOS is a premium, officially licensed gas blowback airsoft pistol manufactured by GHK. It combines the familiar full-size Glock 17 Gen5 platform with modern MOS optics compatibility, a lightweight construction and GHK’s distinctive hammerless internal system.
The slide is manufactured from injection-formed aluminium alloy and finished with CNC machining for accurate dimensions and clean detailing. The slide, outer barrel and MOS cover feature a durable Cerakote finish, which improves wear resistance while giving the pistol a high-quality and authentic appearance.
Unlike conventional gas blowback pistols that use a traditional hammer system, the GHK Glock 17 Gen5 MOS features a patented hammerless, all-steel fire control system. The design eliminates hammer resistance against the slide, helping the action cycle smoothly. A large one-piece cylinder produces a strong and responsive blowback impulse despite the pistol’s lightweight construction.
The pistol weighs approximately 505 g with the magazine installed, making it noticeably lighter than many conventional metal-slide gas pistols. The lighter moving components support fast cycling and responsive handling, while the full-size Gen5 frame retains the familiar ergonomics, controls and official Glock markings.
The MOS-ready slide allows a miniature red dot sight to be installed using a compatible adapter plate. The adapter plate is available separately, allowing the user to select a plate that matches the desired optic footprint. The pistol can also be used with its mil-spec-style front and rear sights when no optic is installed.
An adjustable TDC hop-up system allows the BB trajectory to be tuned for different BB weights and playing conditions. The pistol is supplied with a 20-round gas magazine and is compatible with GHK Glock 17 Gen3 gas and CO2 magazines. Magazines made for other manufacturers’ Glock replicas may not be compatible.
Note: The red dot sight, MOS adapter plate and gas are not included in the package unless separately specified.
