The 6-24x50SF is a dedicated long range riflescope that offers the precision, the features and the ruggedness serious shooters demand. With an Illuminated X-MOA reticle, the riflescope delivers 60 total MOA internal adjustment travel. Its turrets have 1/4 MOA click graduations yielding 12 MOA (48 clicks) per revolution. The BLACK X1000 6-24x50SF has the reticle placed in the riflescope’s second focal plane, so all holdover corrections, ranging and other measurements using the indicated reticle subtensions should be done at 18x magnification. Like all BLACK riflescopes, it is built with an aircraft grade aluminum alloy 30mm main body tube.
