Effortlessly shrugging off recoil, moisture and darkness! The Viper's status as a premium riflescope won't be as easy to shake. Discover a riflescope with incredible performance features like premium, fully multi-coated optics with 95 percent light transmission, heavy duty Precision Force spring systems and the glass smooth Precision Glide erector system—delivering all this and more at a price that should have pulled a few more hundreds from your wallet than it did.
Note: This scope has a second (SFP) focal plane reticle, meaning the reticle stays at the same size no matter what magnification you are on. We also carry this product with a first (FFP) focal plane reticle—an important option for many precision shooters.Optical Features
