Eotech HWS 512 Holographic Sight

The EOTech HWS 512 holographic sight is built for shooters who need immediate target acquisition without adding complexity to the rifle. Its signature holographic reticle stays fast and intuitive at speed, while the compact 5.6" x 2.0" x 2.5" footprint and 11.5 oz weight keep your setup balanced on carbines and patrol rifles.

Powered by two standard AA batteries, the 512 runs on lithium, alkaline, or rechargeable cells—so you can source power anywhere and stay in the fight longer. Expect up to 2,500 continuous hours on lithium (2,200 on alkaline) at a nominal setting, with 20 daylight brightness levels for clear reticle visibility from indoor lighting to full sun. Precise 0.5 MOA windage and elevation clicks let you dial your zero with confidence, and the integrated mount clamps directly to a 1" Weaver or MIL-STD-1913 Picatinny rail.

Use it for dynamic range work, home defense, duty use, or training in harsh weather—rated water resistant to 10 ft and operating from -40°F to 140°F. Made in the USA, the EOTech 512 is the most popular HWS model for shooters who don’t need night-vision compatibility but demand rugged, repeatable performance.
