The EOTech 512 is a 1x holographic weapon sight with a 68 MOA ring around a 1 MOA red dot, built in EOTech's long 5-series housing and powered by two ordinary AA batteries.
EOTech call it the most popular HWS in the range: the holographic sight picture, running on batteries you can buy anywhere.
The 512 has 20 daylight brightness settings, rear-mounted push buttons and 0.5 MOA per click windage and elevation. It clamps to a 1in Weaver or MIL-STD-1913 rail on a cross-bolt, measures 5.6 x 2.0 x 2.5 in and weighs 11.5 oz (326 g). EOTech rate it water resistant to 10 ft (3 m) and quote up to 2,500 hours from lithium AAs, or 2,200 hours from alkalines, at setting 12. It is made in the USA.
Because the reticle is a hologram rather than a reflected LED, the ring and dot stay usable through a smeared, wet or partly blocked window, and EOTech project the reticle at 200 m to minimise parallax. The 68 MOA ring is the fast close-range reference; the 1 MOA dot is for precision. The one thing it does not do is night vision — there are no NV brightness settings, so if you shoot behind an image intensifier, the EOTech 552 is the same sight with them.
Any 1in Weaver or MIL-STD-1913 Picatinny rail, which covers AR-15 flat-tops, rail-equipped shotguns and most modern carbines. EOTech calibrate the reticle's aiming points for .223 62 gr at 2,900 fps; with a shotgun the ring roughly approximates the shot pattern, which varies with choke and cartridge. To add magnification, pair it with an EOTech G33 3x magnifier.

Two standard 1.5 V AA batteries. EOTech say lithium, alkaline or rechargeable AAs all work, and quote up to 2,500 hours on lithium or 2,200 hours on alkaline at brightness setting 12.
No. The 512 has 20 daylight brightness settings and no night vision settings. If you need to use the sight behind a night vision device, the <a href="/products/eotech-552-holographic-weapon-sight-night-vision-68-moa-ring-1-moa-dot">EOTech 552</a> is the equivalent model with 10 extra NV settings.
A red dot reflects an LED off the front lens. A holographic sight like the 512 reconstructs the reticle as a hologram, so it stays usable even if the window is smeared or partly obscured, and EOTech project it at 200 m to minimise parallax.
It clamps to any 1in Weaver or MIL-STD-1913 Picatinny rail with a cross-bolt, which covers AR-15 flat-tops and most railed carbines and shotguns.
