Installation of Equipment
MOUNTING
The Reflex Sight is equipped with mounting hardware to attach to a MIL-STD-1913 Picatinny
style rail. To achieve the best results and accuracy, the HWS must be mounted properly. The
Picatinny 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 Picatinny rail be
installed by a qualified gunsmith. To mount the sight, please follow these steps.
