UMAREX Glock 19 Gen5 GBB Airsoft Pistol — Black

The UMAREX Glock 19 Gen5 GBB is a gas-powered airsoft gun with blowback, developed in collaboration with VFC and dimensionally faithful to the original pistol: 185 mm overall length and 610 g weight, with an ABS frame and metal components. It is aimed at players involved in dynamic airsoft shooting, technical training and milsim who are looking for a compact and easy-to-handle airsoft gun with realistic operation.

The gas blowback system delivers recoil sensation and slide movement with every shot — elements that set training with this airsoft gun apart from shooting with spring or AEG systems. The metal hop-up chamber ensures a stable adjustment over time: by setting the hop-up you can compensate for trajectory drop and work with BBs from 0.28 g to 0.32 g, the recommended weight to make the most of the muzzle velocity, which sits at around 95 m/s with 0.20 g BBs. The inner barrel measures 85 mm.

The metal mid-cap magazine holds 19 BBs and is compatible with Green Gas and low-pressure gases such as ASG ULTRAAIR Green Power Gas. Using CO2 magazines requires replacing the recoil spring with the reinforced one included in the box. This distinction matters: the stock version is optimised for medium-pressure gas, and forcing high-pressure gas through it without mechanical adjustment can damage the seals. The RIS/Picatinny rail beneath the barrel allows the mounting of torches and compact aiming devices. The barrel thread is 11 mm clockwise, compatible with the majority of airsoft suppressors and adapters. The airsoft gun requires periodic lubrication with silicone oil on seals, moving parts and the trigger mechanism.

Key features

• Real blowback with metal slide: the operating cycle is realistic and useful for training in malfunction drills and magazine changes.
