Green Tritium Outline Orange Square (non trit) REAR for Glock Gen 1-4

The Green Tritium Outline Orange Square (non trit) REAR for Glock Gen 1-4 is a precision rear sight designed for shooters who demand fast target acquisition and reliable low-light performance. AmeriGlo's hybrid illumination design combines self-luminous tritium with a non-tritium orange square outline, creating a sight picture that remains visible in complete darkness while maintaining clarity in daylight conditions. This rear sight is engineered specifically for Glock Gen 1 through Gen 4 platforms, making it an ideal upgrade for duty, defensive, or sport shooting applications where sight visibility is non-negotiable.

The tritium element within the sight delivers consistent luminosity for approximately 12+ years without requiring batteries or external charging, while the orange square outline surrounding the tritium provides a bold visual reference in daylight shooting. This two-tone contrast system allows the shooter's eye to quickly locate the sight picture under any lighting condition—the tritium glows independently at night, and the orange outline enhances contrast during high-light environments. The sight is engineered to Glock specifications and installs as a direct replacement for factory rear sights on Gen 1-4 Glock models, requiring only standard armorer tools and basic installation knowledge.

Law enforcement, military, armed citizens, and competitive shooters benefit from this sight's consistent performance across lighting transitions. The rear sight pairs seamlessly with AmeriGlo front sights to create a complete sight system, and installation takes minutes on any Glock Gen 1-4 platform including the 17, 19, 22, 23, and most subcompact variants. Tactical professionals and recreational shooters alike rely on tritium sights to maintain target focus when conditions shift from daylight to darkness, making this rear sight a practical investment for serious firearms users.
