Vortex Diamondback Rifle Scopes feature solid, one-piece aircraft grade aluminum alloy construction which makes them very strong and more resistant to even the heaviest recoil. They are purged with Argon gas which eliminates internal fogging and retains its protective properties over a wide temperature range. The windage and elevation dials also pop-up for fast and easy adjustments. Protective lens covers are included.Specifications and Features:Finish Matte BlackWaterproof YesWeight 16.2 OunceTube Diameter 1"Power Variability VariableMinimum Power 3.5Maximum Power 10Adjustment Click Value 1/4 MOAAdjustment Type ClickExposed Turrets NoFinger Adjustable Turrets YesTurrets Resettable to Zero YesZero Stop NoTurret Height LowFast Focus Eye Piece YesLens Coating Fully Multi-CoatedWarranty Vortex VIP Lifetime WarrantyRings Included NoSun Shade Included NoLens Covers Included YesReticle Please selectReticle Construction WireIlluminated Reticle NoHoldover Reticle YesReticle Focal Plane Location 2ndParallax Adjustment FixedFog Proof YesShock Proof Yes
