Glock 17 Gen 4 MOS 9MM Semi Auto Pistol, Threaded Barrel, With Vism Flip Up Reflex Sight

GLOCK 17 in MOS Configuration With Threaded Barrel & Pop Up Reflex Sight

As quick-targeting reflex sights have made their way onto defensive carry guns, GLOCK developed the G19 Gen4 in MOS configuration. This makes mounting a reflex sight on the pistol’s slide without the need for a new slide or separate mounting System quick and easy. Adding to that, the modular back strap system makes it possible to instantly customize its grip to accommodate any hand size. The reversible magazine catch makes it ideal for left and right-handed shooters.

The FlipDot Patented folding Red dot reflex lens (22mm X 16mm) folds down flat when not in use. With a push of a button the FlipDot lens flips up and automatically turns on. The 3 MOA Red dot is fully adjustable for windage and elevation. Folding the lens down turns the optic off.

Integrated into the FlipDot body is a backup rear sight and on the bottom of the FlipDot lens frame is a backup front sight post. The FlipDot backup iron sights function when the lens is deployed in the up position, through the glass lens. The FlipDot backup iron sights will cowitness with most of the Glock® suppressor height sights installed on the slide (if equipped).

Includes a Glock® MOS compatible mounting plate, *spare MOS mounting screws, 2mm optic spacer for RMR® mounting applications, spare CR2032 battery, optics cover, and mounting & adjustment tools. *Glock® MOS compatible mounting screws are included. Optic mounting screws for other types of slides are not included, please source the mounting screws from the slide manufacturer for an RMR® type optic for non Glock® MOS slides. Note: the use of the 2mm optic spacer for RMR® mounting applications may require longer optic mounting screws. Please follow mounting instructions in the FlipDot manual.
