HIVIZ Fiber Optic Target Rear Sight for Glock (Excludes 42, 43, 43X, 48, MOS) - Green, Red, White Options

The HIVIZ Fiber Optic Target Rear Sight for Glock brings a rugged, high-visibility solution to your duty or range gun. Designed for most Glock models, this fully adjustable rear sight uses bright fiber optic technology to cut through variable lighting and keep your target picture sharp when it counts. If you run a standard Glock and want to upgrade from the factory plastic sights without going full-rail or optics, this is a straightforward swap that works with HIVIZ's interchangeable LitePipe ecosystem.

The rear sight pairs with HIVIZ's Front Sight (model GLAD201, sold separately) to complete the system. The real differentiator here is the interchangeable LitePipe—you get green, red, and white fiber options in the box, so you can tune your sight picture to the lighting conditions where you actually shoot. That flexibility beats fixed-color or all-metal alternatives, especially if you split time between indoor range and outdoor hunting or tactical scenarios.

Installation is straightforward on supported Glock models; just note the excluded platforms (42, 43, 43X, 48, and MOS variants). Once mounted, the fully adjustable design lets you dial in your point of aim without guesswork. Whether you're working on precision at the bench or building a reliable duty carry setup, this sight gives you the visibility and adjustability that factory Glock sights don't.
