The 558 is compatible with Gen-I-IIInight vision devices and features an adjustable, locking quick detach mount that offers instant removal. The operational buttons are located on the side of the sight making this optic ideal for use with EOTech switch-to-side magnifiers. The major advantage is extremely rapid reticle-on-target acquisition. Operators can quickly acquire the target and reticle in the same focal plane for fast and accurate shot placement. The sight can be used as a bright open reticle image or a fine dot which is limited only by the acuity of the shooter’s eye. The heads-up display window allows an undistorted and unrestricted view of the target.
While in the NV mode, the sight is undetectable by night vision equipment. The HWS® can be positioned behind night vision systems without any “bloom” on the target area.
