The Hawke Sport HD IR Rimfire scope brings 200-yard accuracy to the most popular rifle in the world by using an innovative yet simple reticle design. At 50 yards the Sport HD IR Rimfire provides 25-yard aim points from 50 to 200 yards, giving the user downrange accuracy never expected from a .22 rifle. As a bonus, there is no need to memorize aim points, as the yardages are etched directly onto the glass of the reticle. Designed to be accurate at 9X magnification for ammunition shooting at or near 1,300 fps, the 3-9×40 chassis design is easy to use and reliable.

By decreasing the magnification it is also possible to calibrate the scope to subsonic ammunition. In addition to the BDC capabilities, the reticle is also illuminated with five levels of red and green to match ambient light conditions.
