Sightron engineers gave the classic hunting riflescope a complete overhaul when creating the the Sightron S1 4-12x40mm G2 riflescope. Using modern optical designs and manufacturing techniques the S1 4-12x40mm G2 provides clear and sharp views in just about any lighting due to Sightron�s all-glass lenses and exclusive MC-333 lens coatings. Sightron�s Precision Focus Eyepiece provides a customizable sight picture with extended eye relief. A compact lightweight 1-inch aircraft aluminum tube houses an all-new erector tube system which is nitrogen charged O-ring sealed providing IPX7 waterproof and fogproof performance and construction is 1000G rated shockproof. All of this provides the ability to take the hunt to the field earlier and later than ever and handle whatever obstacles Mother Nature throws at you. - Magnification: 4-12x - Objective Lens Diameter: 40mm - Eye Relief: 3.5 in-3.2 in - Field of View: 29.97 ft-9.95 ft - Tube Size: 1-inch - Turret Style: Capped Hunting - Zero Stop: No - Click Value: 1/4 MOA - Minutes Per Revolution: 15 MOA - Max Elevation Adjustment: 60 MOA - Max Windage Adjustment: 60 MOA - Parallax Setting: Parallax Free (100 Yards) - Focus Type: Fixed - Reticle Type: Duplex - Focal Plane: Second Focal Plane - Illumination: No - Finish: Matte Black - Waterproof: Yes IPX7 rated - Anti-Reflection Tech: MC-333 Multi-Coatings - Fog Proof: Yes - Length: 12.3 inches - Weight: 13.6 ounces - Sunshade: Not Included
