The Thunder Ranch 1-6×24 was developed in conjunction with the infamous Clint Smith. His input and data are what birthed the THR bullet drop compensator reticle found in this optic. The daylight bright green illumination was a must for Clint. His time as a battle-hardened Marine along with his time as a law enforcement officer make his input invaluable. One look at this incredible scope and you’ll know why he put his name on it. - PRODUCT FEATURES: - Featuring capped zero resettable turrets - 2/10 MRAD Windage and Elevation Adjustment - Integrated Removable Throw Lever - 6 levels of green illumination featuring on/off between each level - Fast-Focus Eyepiece - 100% Waterproof Fog Proof and Shockproof - Magnification: 1-6 - Parallax Adjustment: Fixed at 100 yards - Tube Diameter: 30mm - Objective Lens Diameter: 24mm - Focal Lens Position: Second Focal Plane - Lens Coating: Fully Multi-Coated Full Wide Band Waterproof Coated Low Light Enhancement - Reticle: THR - Field of View at 100 yds: 111.2ft-18.33ft - Material: 6061-T6 - Eye Relief: 3.5in/90mm - Exit Pupil: Low 8.5 mm-High 4mm - Click Value at 100 yds/mm: 2/10th MRAD - Adjustment Range: 40 MRAD - Mounting Length: 6.25in/158mm - Length: 10.25in/260mm - Weight: 22.2oz/629g - Included Items: Flip Up Lens Covers Lens Cloth Allen Wrench
