The Burris Fullfield scopes were game-changing when they first hit the market.They had a wider field-of-view than other scopes, and were manufactured with a very impressive set of features, like steel-on-steel knob construction for added reliability in the field. And bullet-drop compensating reticles for easy accuracy.The Burris Fullfield E1 is the continuation of that. The reticles have been fine-tuned for added accuracy. The power ring zoom has been updated to make it easier to turn and to keep the lens covers from turning. But we havent forgotten any of the things that made this scope line so popular.3-9x is the absolute classic size for American hunters in all sorts of terrain and conditions.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.SpecificationsDescription Non-illuminatedReticles Ballistic Plex E1Colour Matte BlackKnob Style Capped HunterIllumination noMagnification 3-9Objective Lens Diameter 48 mmClear Objective Lens Diameter 40 mmOcular Lens Diameter 39 mmFocal Plane RFPMain Tube Size 1 in.Field of View 33 low 13 high (ft. @ 100 yds.)Eye Relief 3.1 3.4 in.Exit Pupil 13 low 5 high (mm)Click Value 1/4 MOAElevation Adjustment, Total Capability 50 MOAParallax/Focus NoneAdjustable Parallax NoneFinish MatteLength 12.2\
