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 rifle scope's second focal plane, so all holdover corrections, ranging and other measurements using the indicated reticle sub-tensions should be done at 18x magnification. Like all BLACK riflescopes, it is built with an aircraft grade aluminum alloy 30mm main body tube.
