Description And features

Delivering day or night command and control with convenient AA battery power. Our Model 558™ HWS works with all Gen I-III night vision devices and features an adjustable, locking, quick-detach mount for instant removal. Ergonomic, side operational buttons make this HWS ideal for use with EOTECH’s quick, flip-to-side magnifiers and adjustment activation without removing your strong hand.

EOTECH’s unique reticle patterns are a critical to delivering fast target acquisition and MOA accuracy at any range. EOTECH reticles feature a 68 MOA ring surrounding a 1 MOA center dot allowing the shooter to quickly pick up and lock on a target.

-Our most popular reticle offered, the 68 MOA ring with 1 MOA dot provides three usable aiming points. The aiming points above are based on the following load: .223 cal. 62 gr. 2,900 vel. When using other loads and calibers, the operator will have to establish the ranges associated with the aiming points. When using a shotgun, the 68 MOA ring can be used to represent shot patterns but will vary based on choke and shell selection. For ordering this reticle, the model codes will end in -0.
