Umarex Glock 17 Gen 5 MOS Pellet is designed for recreational shooters who want to make no compromises when it comes to precision, realism and individuality. The innovative chain magazine and rifled barrel give the 4.5 mm pellets a much more stable trajectory and better precision than steel BBs. The powerful blowback simulates a recoil with every shot, providing an authentic shooting experience. The trigger safety prevents accidental firing and is supplemented by a manual sliding safety. Another special feature of the GLOCK 17 Gen5 is the Modular Optic System (MOS). The metal slide of the pistol has an integrated interface for red dot sights that can be installed on separately available adapter plates. Users have a choice of red dot sights with Docter, Trijicon, C-More and Leupold footprints. The Umarex Glock 17 Gen 5 MOS Pellet is exactly dimensioned, guaranteeing that the Weaver rail can hold accessories like weapon lights and lasers and that the pistol is compatible with standard holsters.
