The Dr. Black Aluminum Fiber Optic Rear Sight is a premium sighting upgrade designed specifically for the Tokyo Marui Hi-Capa 5.1 GBB platform. While standard plastic or heavy zinc-alloy sights can be bulky and difficult to track in low light, this Dr. Black model combines lightweight CNC precision with high-visibility fiber optics for instantaneous target acquisition. Key Performance Features Precision CNC Aluminum Construction: Machined from high-grade aluminum, this rear sight offers superior durability compared to stock plastic sights while remaining significantly lighter than traditional die-cast metal versions. This reduction in "top-heavy" weight helps maintain a balanced slide cycle. High-Visibility Fiber Optic System: Engineered to gather ambient light and channel it into two bright glowing dots. This allows shooters to track their sights much faster during rapid-fire strings and transitions, especially in indoor or low-light CQB environments. Dual-Color Customization: Each sight includes both Green and Orange fiber optic rods. This allows you to choose the color that best suits your vision or environment, or even mix-and-match for a custom high-contrast look. True Drop-In Installation: Designed as a direct replacement for the Tokyo Marui (TM) Hi-Capa 5.1 rear sight. It utilizes the standard mounting points, ensuring a secure and wobble-free fit without the need for complex modifications or filing. Skeletonized Profile: Consistent with Dr. Black’s performance-first philosophy, the sight features a sleek, low-profile design that minimizes snagging on holsters while providing a crisp, clear sight picture. Technical Specifications Feature Specification Platform Tokyo Marui Hi-Capa 5.1 GBB Material 6061 CNC Aluminum Optic Type Fiber Optic (Light-Gathering) Included Colors Green Orange Rods Installation Drop-In (Direct Replacement) Compatibility TM, WE, AW, and TM-Spec Custom Slides
