When bullet drop and windage information are of the utmost importance, the Vortex Viper HS 2.5-10x44mm Rifle Scope delivers everything you need to make the shot. The Dead-Hold BDC reticle helps eliminate guesswork on holdover and windage corrections, making it perfect for hunting/shooting at varying ranges where estimating holdover is a concern. The Viper HS features an exposed, target-style elevation turret that's built for dialing elevation at extended ranges, plus CRS zero stop for easy return to zero. MAG-View fiber optic technology provides a highly visible reference point for magnification setting, and a patented Radius Bar fiber optic turret rotation indicator provides a highly visible and tactile point of reference for turret rotations. The Viper HS features XD extra-low dispersion glass and proprietary XR coatings for clear, bright images, superior edge to edge clarity and true color. The single-piece, hard anodized tube features a capped windage turret that maintains the Scope's sleek lines and prevents it from hanging up on clothing, rifle cases or scabbards. Rugged construction, O-ring seals and argon purging ensure shockproof waterproof, fogproof performance for every situation. With the Vortex VIP Warranty, You Get a Very Important Promise.
