The illuminated FireDot Duplex reticle aids in quick target acquisition and low-light visibility. One standout feature is the CDS-ZL2 turret system, allowing precise elevation adjustments with a push-button lock to prevent accidental changes, which is especially useful for shooters who need consistent zeroing. The side focus parallax adjustment helps maintain a sharp sight picture, reducing eye strain and improving accuracy. Eye relief is comfortable, thanks to the 30mm tube size, accommodating different shooting positions. Leupold's Guard-ion lens coating resists dirt and water, enhancing maintenance ease and clarity.
