The field proven Viper HS LR has gained another extraordinary tool with the addition of the First Focal Plane Reticle. The HS LR was designed for long range shooting and now you can extend that range even further. The exposed elevation turret features ½ MOA adjustments with 24 MOA/Revolution and 75 total MOA of travel. With a generous eye relief and ample field of view, the HS LR FFP is in a class of its own. The 30mm 1-piece tube is 100% weatherproof and the extra low dispersion glass is XR fully multi-coated for increased light transmission and maximum brightness. The HS LR also comes equipped with the CRS Zero stop to prevent dialing more than one rotation below your zero when dialing for extreme long range. Other outstanding features include side focus, MAG-View fiber optics to verify the magnification setting even under low light, ArmorTek scratch resistant lens coating, fast focus eye piece and the HS LR is covered by the Vortex VIP Unconditional Lifetime Warranty.
