Description The Buckmasters Rangefinder and Riflescopes were inspired by Jackie Bushman to bring the performance of SIG SAUER Electro-Optics at a value that is within reach for every hunter. The riflescopes feature a custom Buckmasters Bullet Drop Compensation (BDC) reticle that has holdover dots out to 500 yards. The rangefinder will provide lightning-fast-ranging performance in a vivid red illuminated display optimized for low light hunting. As an extra value, the rangefinder can be used in "Buckmasters Mode" which comes equipped with 8 onboard ballistic groups, so the rangefinder can indicate which Buckmasters BDC holdover dot to use in your riflescope.PRODUCT DETAIL:Objective Lens Diameter: 50 mm Magnification: 3 - 9 x Reticle: BDC Tube Diameter: 1 in Reticle Focal Plane: Second Focal Plane (SFP) Exit Pupil: 5.55 - 16.06 mm Battery Type: Stand Alone Lithium Battery Quantity: 1 Field of View, Linear: 11.3 - 34.1 ft at 100 yds Eye Relief: 3.85 - 4.17 in Color: Black Weight: 450 g Adjustment Click Value: 0.25 MOA Magnification Type: Variable W/E Travel at 100 Yds: 60 MOA
