Umarex Glock 17 Gen.4 Pistol Replica GREEN GAS

The pistol  features a Blow-Back system which via slide’s recoil imitates the experience of firing a real firearm with every shot. Similarly to the live firearm, once the last BB has been fired, the slide remains locked in the rear position. In order to gain access to the Hop-Up adjustment knob, it is necessary to remove the slide.
