From close quarters to long range target engagements, the Leupold Mark 8 CQBSS 1.1-8x24mm incorporates everything Military, Law Enforcement and Competition shooters need into one extremely versatile riflescope. The illuminated front focal plane reticles provide accurate range estimation throughout the entire zoom range. Eight brightness settings ensure optimal visibility of the illuminated reticle in all lighting conditions and are compatible with night vision devices. An off position between each numbered brightness setting ensures long battery life and nearly instant return to the desired reticle intensity. The 34mm Maintube and twin bias spring erector system provides over 40 Milliradians of total windage and elevation adjustment. Auto-Locking Pinch & Turn 1/10th Mil click adjustments make precise corrections quick and easy, yet eliminate accidental movement in the field. Quick change BDC (Bullet Drop Compensation) rings allow the scope to be matched to virtually any ammunition for long range precision. The Mark 8 CQBSS is completely waterproof, fog proof, and backed by the Legendary Leupold Mark 4 Warranty. The ultimate blend of rapid target acquisition, precision, and rugged durability, the Mark 8 CQBSS eliminates compromise.Index Matched Lens SystemDiamondCoat 22nd Generation Argon/Krypton WaterproofingGenerous EyeboxBlackened Lens EdgesExtreme Fast-Focus EyepieceLockable Fast-Focus Eyepiece8:1 Zoom RatioFront Focal Plane (FFP)Tactile Power SelectorM5B1 Adjustments34mm Maintube100% Waterproof and FogproofBullet Drop CompensationAlumina Threaded Lens CoversBLEMISHED products may or may not include accessories.
