2.5 Installation of Equipment
MOUNTING
The HWS® is equipped with mounting hardware to attach to a 1” (25.4mm) Weaver or MIL-STD-1913
Picatinny style rail. To achieve the best results and accuracy, the HWS® must be mounted properly. The
rail needs to be as parallel as possible to the bore to permit the maximum elevation and windage
adjustments. If it is required, it is strongly recommend that the rail be installed by a qualified gun-
smith. To mount the sight, please follow these steps.
Turn the Knurled Weaver bolt counterclockwise to back the bolt out of the weaver lock. Do not
back the bolt all of the way out of the lock, only enough for the base to sit properly on the rail.
Turn the Knurled Weaver bolt clockwise, drawing the weaver lock into the rail until resistance
is felt. Using a coin, (a U.S. nickel or similar size is recommended), rotate the bolt head an
additional ¾ turn to fully tighten. This is equivalent to approximately 17 in-lb (0.2 kgm) of
torque.
2.6 Zeroing Procedures
Once the weapon’s iron sights have been zeroed, please refer to the section on Windage and Elevation
Adjustments (Section 2.1.5) to zero the HWS®. The following are some additional reference aids that
can be used during the zeroing process.
