3-9x is the absolute classic size for American hunters in all sorts of terrain and conditions. Burris offers two 3-9x40mm scopes in the Fullfield E1 family, one features an illuminated reticle, one is non-illuminated. The illuminated model features 10 brightness settings. This state-of-the-art reticle has cascading windage and elevation dots, so you can execute long-range shots out to 500 yards in still or windy conditions. The riflescope is resistant to a lifetime of field use, heavy recoil, and harsh vibration.
