The Holographic Hybrid Sight I (HHS I) features an EXPS3-4 with a G33.STS magnifier. It has great utility for any shooter, whose target ranges vary from close to mid-range.
The HHS I provides a solution for engaging threats in close-quarter combat situations, then quickly transitions to a 600-meter targeting or surveillance situation. A quick switch-to-side (STS) mount offers simple, fast disengagement of the G33 magnifier. The durable, night-vision-compatible system offers wide-field optical performance with superior light transmission for visibility in extreme low-light conditions.
I bought this sight for my kriss vector, it arrived super fast and in excellent condition! Quality of the sight is excellent, its super easy to put on and adjust for proper eye relief. I enjoy the interchangeability of close and medium range targets!
