The NX8 F1 1-8x 24mm is a class leading, compact and lightweight riflescope optimized for short to mid-range shooting. At only 8.75" in length and 17 ounces, this riflescope adds minimal size and weight but delivers superior optics and trusted Nightforce performance to any rifle. With the daylight visible center red dot users can engage targets with speed like a red-dot sight, but as targets increase in distance the intelligent FC-Mil and FC-MOA first focal plane reticles provide precise hold points. For those preferring to dial for long shots, the ZeroStop elevation adjustment allows for a rapid and positive return to zero. Adjustments are a true 2/10 Mil-Radian or 1/2 MOA. To aid in fast magnification adjustments, a built-in Power Throw Lever (PTL) is included.Specifications and Features: Adjustment Click Value: 1/2 MOA Adjustment Type: Click Battery Type: CR2032 Battery: CR2032 Exit Pupil Diameter: 7.9-3.0 Millimeter Exposed Turrets: Yes Eye Relief: 3.75 Inches Eyepiece Bell to Objective Bell Length (B): 5.67 Inches Fast Focus Eye Piece: Yes Rings Included: No Shock Proof: Yes Sun Shade Included: No Tube Diameter: 30mm Turret Height: Medium Turrets Resettable to Zero: Yes Warranty: Limited Lifetime Waterproof: Yes Zero Stop: Yes
