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.
