The Umarex Glock 17 Gen 5 MOS BB Blowback is an optics upgrade of one of the most popular polymer pistols in the world. The Modular Optic System (MOS) permits mounting of red dot sights with Docter, Trijicon, C-More and Leupold footprints via adapter plates on the slide, which are supplied as standard. The integrated interface for a red dot sight is part of the CNC-milled aluminum slide, which simulates a strong recoil by means of the blowback with every shot. Gen5-typical features of this successful modern model ensure top performance. This is a full-size pistol, with a large frame and a long sight radius. The sights have high-contrast markings. With its ambidextrous slide stop lever and reversible magazine release the GLOCK 17 Gen5 MOS is also the first choice of left-handers. The authentic trigger safety prevents accidental firing. The Weaver rail on the dust cover makes the GLOCK compatible with standard accessories like weapon lights and lasers. The 17-round all-in-one magazine also holds the 12-g CO2 capsule.
