The best just got better. The 518^™ offers all the features of EOTECH’s top-tier EXPS sight, now powered by easy-to-find AA batteries. With side-mounted buttons and a quick-detach lever, it allows close positioning to a magnifier, saving valuable rail space without compromising performance.

EOTECH HWS^® optics use advanced holography—not LED projection—to deliver a faster, clearer, and more accurate sight picture. Designed for speed, precision, and situational awareness that standard red dots can’t match.

Reticles

• 0-RETICLE The 68 MOA speed ring with a 1 MOA dot enables fast target acquisition and provides three aiming points, calibrated for .223 Cal. 62 Gr., 2,900 Vel. Other calibers can be used by determining the ranges. With shotguns, the ring approximates shot patterns, which vary based on choke and shell type.

   

Features

• MAINTAIN PRECISION HWS^® holographic optics let you view the reticle and target simultaneously for quicker, more intuitive target acquisition.

• NEVER OUT OF THE FIGHT The HWS^® continues to perform with precision even when the window is damaged or obscured, proving its reliability in the most demanding environments.

• MINIMIZE PARALLAX By projecting a holographic reticle at 200m, the HWS^® minimizes parallax—making it the Close Combat Optic of choice for USSOCOM.

• MADE IN THE USA Built in the USA. Trusted worldwide. Every HWS^® is crafted by American hands with precision and pride.
