HiViz GLLW11 LiteWave Green Fiber Optic Rear Sight Glock 42/43

The HiViz GLLW11 LiteWave rear sight transforms sight acquisition on Glock 42 and 43 pistols with bright green fiber optic technology. This precision-machined sight eliminates the guesswork of traditional three-dot systems by providing a clear, contrasting sight picture in all lighting conditions.

What Makes This Different

Unlike standard polymer rear sights, the LiteWave system uses a single green fiber optic rod that creates a bright horizontal line across the sight notch. This design naturally draws the eye to proper sight alignment faster than conventional white dots. The fiber optic element gathers ambient light during daylight hours and remains visible in low-light conditions where standard sights fade into darkness.

Key Features

• Bright green fiber optic rod for enhanced visibility in all lighting conditions
• Precision CNC-machined steel construction with protective sight walls
• Direct replacement for factory Glock 42 and 43 rear sights
• Low-profile design maintains holster compatibility
• Dovetail mounting system with secure lock-up
• Replaceable fiber optic element for long-term serviceability
• Matte black finish reduces glare and reflection

The LiteWave rear sight excels in competitive shooting environments where fast target acquisition determines match outcomes. Law enforcement officers benefit from the improved visibility during low-light encounters common in duty situations. The fiber optic technology maintains brightness without batteries or external light sources, making it reliable for concealed carry applications where the sight may remain covered for extended periods.
