When you want quick target acquisition at both short and medium ranges you need additional magnification. The Athlon prism red dot scopes give you great versatility. This device is equipped with a prism for a crisp, vivid image. The prism-based design allows for a more compact scope without sacrificing optical quality. With this longer focal length it can achieve the magnification needed to reach out and touch targets at longer ranges. The Athlon prism red dots are nitrogen-filled, fog proof and shock proof, allowing for reliable use in a wide range of environments. Featuring a selectable red/green illuminated reticle with multiple intensity levels to match your specific conditions. The reticles are etched directly on the glass to make sure you have consistent point-of-aim at all times. Whether you have the illumination on or off, the reticle is always visible.
