Byrna Technologies HD/SD/LE/SDXL/EP Pro-Fiber Top Cover Features The Byrna Technologies Pro-Fiber Top Cover replaces the factory top cover with a version built around genuine fiber optic sights front and rear. These fiber optic elements gather and concentrate ambient light into a bright easily visible aiming point which speeds up target acquisition compared to standard sights. Unlike conventional sight channels that can wash out or disappear in bright sunlight or dim rooms fiber optic sights stay consistently visible whether training indoors outdoors or in changing light. This gives shooters a more dependable sight picture across a wider range of real-world conditions. Molded from durable black polymer the Pro-Fiber Top Cover measures 8.70 inches in length and 1.50 inches in height matching the factory dimensions of its compatible hosts. It is designed to fit the Byrna HD SD LE SDXL and EP launchers giving owners of any of those models a direct upgrade path without needing a different cover for each. At only 0.29 pounds the cover adds negligible weight to the launcher while meaningfully improving sight performance. This makes the Byrna Technologies Pro-Fiber Top Cover a practical sighting upgrade for sale at GrabAGun.
