The EOTech Complete System EXPS3-4 HWS G45 STS Mount delivers a versatile holographic hybrid sighting solution designed for Close-Quarters Combat and precision at 600 meters, blending an EXPS3-4 with a 5X G45 magnifier to adapt to rapid target transitions. Its Switch-To-Side (STS) mount enables instant, tool-free disengagement of the magnifier, offering seamless field changes from close-range engagements to longer-range observation. This durable, night vision-compatible system provides a wide field of view and fog-resistant internal optics for reliable visibility in extreme low-light conditions, while the 0.5 MOA per click windage and elevation adjustments ensure precise dial-in. With 20 daylight brightness settings and 10 additional settings for Gen I through III+ night vision devices, operators can tailor clarity across varying environments, aided by a fixed 5X magnification, 66 mm eye relief, and a 4.4-degree field of view when the magnifier is in use. The package includes the HHS V assembly, a protective case, quick-start guide, warranty registration, and a CR123 battery, with a robust 24 oz (680 g) weight and 33 ft (10 m) water resistance. Made in the USA, this system is designed for Weaver or MIL-STD-1913 rails and supports reliable performance from first light to deep into the night.
