Burris' Fullfield E1 Riflescope features a state-of-the-art reticle that has cascading windage and elevation dots, so you can execute long-range shots out to 500 yards in still or windy conditions. The lenses are multi-coated for glare resistance and maximum efficiency in low-light hunting conditions. This scope is housed in a 1-piece, stress-free tube and its internal assembly is double spring-tensioned for shockproofing. Its separated power ring and eyepiece accepts flip-up lens caps.
