EOTECH HWS 512 is a slick, highly rugged and capable, full-featured holographic sight from EOTech of Ann Arbor, Michigan. It makes target acquisition fast. Very fast.

The company founded as a spinoff of Environmental Research Institute of Michigan (ERIM) of the University of Michigan, and EOTech sights are Made in USA. The EO in EOTech stands for electro-optic, and that’s what they focus on. HWS stands for Holographic Weapon Sight.

Premium technology commands premium prices. Brand new, EOTech 512s can cost as much as a good number of semi-auto handguns. There are actually four units in the lineup. The 512 is the base version. But even this one is very well-equipped with many thoughtful features and excellent ergonomics.

The 512 comes in black; pop in a pair of AA batteries to power it. The batteries can be CR123 Lithium, alkaline, or rechargeable. Alkaline will give you over 2,200 hours of operation while the Lithium batteries should be good for about 2,500 hours.

Primary operations are via a pair of intuitively placed rectangular buttons placed in back making them ambidextrous. The sight has twenty brightness settings, which should easily cover all your daylight target acquisition needs, from sun up to sun down.

The sight is water-resistant in up to 10’ of water and weighs 11.5 ounces. A pair of flat head (or in a pinch, fingernail) adjustable screws adjust the sight for elevation and windage.

This is not a small device. Length is 5.6”, width is 2.5”, and from base to the top of its aluminum hood, the device is 2.5” tall. You can get it with either a 1” Weaver or Picatinny MIL-STD-1913 rail attachment.

The 512 has two aiming reticle options. Reticles ending in “0” have a red 68 MOA ring with 1 MOA red dot. It has three aiming points: 200 yards, 50 yards and 7 yards. Reticles ending in “2” have four aiming points: 500 yards plus 200 yards, 50 yards and 7 yards.

The 512 lacks night vision compatibility. For that, there is always the 552 model, which adds night vision and is water resistant up to 33’ instead of 10’. This model has the same dimensions as the 512. The night vision can be actuated via a switch that’s in back next to the brightness adjustment buttons.

Model 518 is the same as the 512 (and thus water resistant up to 10’ and lacking night vision) but adds a quick detach cam lever. Weight inches up to 13.8 ounces. Model 558 has it all. It is like the 552 plus the quick detach cam lever and weighs 13.8 ounces.

People swear by these sights for good reason. While pricy, they are durable, adjustable and high-performance.
