HD (High Definition) coatings on all lenses reduce reflections. This improves the image brightness and clarity, making the Sport HD range of riflescopes a joy to use. The Sport HD range offers exceptional value for money without compromising optical performance or reliability. Simple. Reliable. Affordable. The compact fast focus eyebell keeps the reticle clear and crisp while the 1/4 MOA fingertip turrets zero the crosshairs - kept firmly in position by a high quality beryllium spring.
