Description
Umarex Glock G45 Gen5 MOS GBB
The Umarex Glock G45 Gen5 MOS GBB is a premium, officially licensed gas blowback airsoft pistol manufactured by GHK. The Glock 45 combines a compact-length slide with a full-size Gen5 grip, offering fast handling, a stable firing grip and excellent control in both indoor and outdoor airsoft use.
The slide is manufactured from aluminium alloy and finished with CNC machining for precise dimensions and clean detailing. The slide, outer barrel and MOS cover feature a durable Cerakote finish, improving resistance to wear while giving the pistol a refined and authentic appearance. Steel internal components and a fiber-reinforced polymer frame create a strong but lightweight overall construction.
At the heart of the pistol is GHK’s patented hammerless, all-steel fire control system. Unlike traditional gas blowback pistols, the slide does not need to overcome the resistance of a conventional hammer during cycling. This allows smoother slide movement, faster operation and a more consistent shooting feel.
A large one-piece cylinder produces a powerful and responsive blowback impulse. Despite the compact 185 mm overall length and approximately 504 g weight, the pistol delivers a strong recoil sensation while remaining quick and easy to handle.
The MOS-ready slide allows a compatible miniature red dot sight to be installed using a separately available adapter plate. This allows the user to select a mounting plate that matches the desired optic footprint. When no optic is installed, the pistol can be used with its fixed mil-spec-style front and rear sights.
The full-size Gen5 grip provides a secure hold and plenty of space for the firing hand, while the shorter slide makes the pistol easier to draw, maneuver and use in confined environments. The frame also includes an accessory rail for compatible weapon lights and other rail-mounted accessories.
The pistol features an adjustable hop-up system and comes with a 20-round gas magazine. The internal design, magazines and many replacement parts are specific to the GHK-manufactured MOS platform.
Compatibility note: The GHK-manufactured Glock G45 Gen5 MOS is built around its own internal design and primarily uses model-specific parts and magazines. Parts, magazines and accessories intended for standard Umarex Glock models should not be assumed to be compatible with this MOS version. Always verify that replacement parts, magazines and optic adapter plates are specifically listed for the GHK Glock G45 Gen5 MOS before purchasing.
Note: The red dot sight, MOS adapter plate and gas are not included in the package unless separately specified.
