AMERIGLO GHOST RING SERIES SIGHT SET: For shooters seeking an alternative to the traditional post and notch sight design, there are AMERIGLO Ghost Ring sights. This unique design utilizes an aperture-style rear sight with two tritium mini-dots and a bright tritium front sight, which leads the eye to automatically center itself in the rear ring while focusing on the front sight. The result: immediate front sight acquisition. This sight set ensures excellent contrast for daylight visibility and illuminated reference points for low-light or no-light situations. This sight set is compatible with Glock Model Gen 5 9mm/.40 and with MOS slides. SPECS: - Fits Make: Glock; - Fits Model: Gen 5 9mm/.40; - Fits MOS Slide: Yes; - Green Front & Rear Tritium Color; - Available with white, orange, and lumigreen outlines.
