Product Description

Power, technology, versatility—the SPECTRA 8X (2.5-20x50i) has it all. Super-zoom technology starting at 2.5x makes shooting close or moving game a breeze while 20x magnification is enough to reach as far as you want. This model features a 50mm objective to keep you in medium (not high) rings, making it more comfortable to use on your rifle for those long-range shots, so long-range magnum shooters will love this scope. The iCONTROL™ microdot illumination built on the standard G4 reticle is sure to speed your target acquisition and allows you to place the reticle in all light and distance situations. This scope comes standard with DoubleHD™ objective lens technology, iCONTROL™ illumination, PASSIONtrac™ turrets to assist your shooting scenario, and a G4i reticle. The turrets, designed for 0.36-inch adjustment at 100 yards (or 0.1 mrad), provide 144 inches of adjustment range. Custom turrets also are available.
