coin, or spent brass to turn. The elevation and windage adjustments are shown in Fig. 5. For both
elevation and windage, each click will change the bullet’s point of impact 1/2 Minute of Angle (MOA),
¼ inch (6.35mm) at 50 yards (45.7m), or ½ inch (12.7mm) at 100 yards (91m). Also, one full rotation of
either knob will change the point of impact 10 MOA, 5 inches (127mm) at 50 yards (45.7m), or 10
inches (254mm) at 100 yards (91m). To move the point of impact UP, turn the elevation adjustment
LEFT. To move the point of impact RIGHT, turn the windage adjustment RIGHT.
The HWS® elevation and windage adjustments are factory collimated with the bore of the rifle parallel
to the mounting rail. The sight should be close to mechanical zero when mounted on a properly
installed rail. Do not turn the adjustments before mounting the sight on the firearm. Be sure to check
that the mount and sight are securely mounted after initial firing
CAUTION – There are 80 minutes of total windage and elevation (40 minutes in each direction) in the
HWS®. There are 80
1 /
2
min. clicks of adjustment from optical center to the limits of windage and
elevation adjustment. To establish optical/mechanical zero, adjust turrets to limit, then return 80
clicks (do this for both the elevation and the windage). When encountering an increase in resistance
in adjustments, the end of the adjustment range has been reached. DO NOT turn the adjustments any
farther, serious damage may occur to the sight.
