Vortex Viper 6.5-20x50 SFP Riflescope, Dead-Hold BDC MOA The Vortex Viper 6.5-20x50 is a high-magnification second focal plane riflescope for hunters who need to reach out. The 6.5x low end keeps western big game in range, while the 20x top end lets you place precise shots on predators over decoys, wary game at distance and small varmints. A 30mm aircraft-grade aluminum tube and capped turrets protect your zero in any terrain. Dead-Hold BDC MOA Reticle The Dead-Hold BDC reticle gives you hold points below the center crosshair for bullet drop and windage marks on the horizontal stadia for wind holds, so you can hold rather than dial when a shot comes up fast. In the second focal plane, the reticle stays the same size at every magnification, keeping the center fine and easy to see. Side Focus Parallax and Fast-Focus Eyepiece A side-mounted parallax knob adjusts from 50 yards to infinity, with range numbers you can read from the shooting position. The fast-focus eyepiece lets you sharpen the reticle quickly, and 3.1 inches of eye relief gives a consistent sight picture behind the scope. Precise, Repeatable Adjustments Tall capped turrets adjust in 1/4 MOA clicks with 12 MOA per rotation and 65 MOA of total elevation and windage travel, giving plenty of range for zeroing and long-range work. The 50mm objective and fully multi-coated lenses deliver strong resolution and contrast in all light conditions, from first light to last.
