A customized elevation turret matches the shooter's ammunition, and holdover becomes a distant memory as the shooter determines range and dials in the exact yardage for precise aiming. A convenient WindMap helps you determine wind hold-off for your 5.56 or 7.62 cartridge. The reticle works seamlessly with the customized elevation turret and WindMap, featuring MOA windage tick marks that compensate for real-life field conditions. Toughness is the redundant design theme, from solid one-piece tubes, to internal double-spring tension assemblies, all designed for rough handling in the field. Customized Elevation Knob & WindMap. Finger-Adjustable, Low-Profile Adjustment Turrets. Double Internal Springs. Positive Steel-On-Steel Adjustments for Repeatable Accuracy. Anti-Reflection Device (ARD). Water, shock & fog proof.
