FASTER. SMARTER. HOLOGRAPHIC.

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.

RETICLE

<strong>0-RETICLE</strong> image

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.

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

 

The HWS® continues to perform with precision even when the window is damaged or obscured, proving its reliability in the most demanding environments.

 

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

 

Built in the USA. Trusted worldwide. Every HWS® is crafted by American hands with precision and pride.

EOTECH 512

"Legendary optic at an affordable price. Two batteries are included and fires right up out of the box. No nicks or dings and it looks great on any kind of rifle or shotgun."

"great service! great product!"

Neil P. (5/5)

Great

"Only have one range day with the optic but I am very happy with the quality, clarity, and accuracy. It gets a bit tall on my PSA AK with a sidemount rail going to fix with a taller cheek rest. Not going to mark the optic down because of my setup. Mounted on a flat top AR upper the optic sits much lower and i can get a good cheek weld."

Eotech for the WIN!!!

"Eotech has been a fan favorite for me!! I have 4 of them on rifles and PDW. Love the holographic donut with dot. Currently run 2 of the HWS 512s. The availability of double A batteries keeps me coming back. Got compliments on how well the SP5 shot with the Eotech on it!!! Will definitely purchase more EOTECHs in the future and always recommend the optics to everyone who will listen!"

"The sight is well made as I expected it would be compared to my first sight from Eotech. It has a good field of view and is adaptable to a magnifier."

Tim R. (5/5)

Great optic and very easy to use

"Fantastic product, have been able to hit center mass in tight groups from 100 yards with no magnification. Highly recommend to anyone to get this over red dots."

James B. (5/5)

Great Sight, Reliable and user friendly

"Great sight! Although the 512 is a little more bulky than others, I prefer it due to the sight being powered by AA batteries which are always readily available."
