The EOTech 518 is a 1x holographic weapon sight with a 68 MOA ring around a 1 MOA red dot, side-mounted buttons and a quick-detach lever mount, powered by two AA batteries.
EOTech sum it up as the features of their top-tier EXPS sight, running on easy-to-find AA batteries.
Putting the buttons on the side lets the 518 sit close to a magnifier, saving rail space, and the quick-detach lever lets you take the sight off and refit it without tools. It has 20 daylight brightness settings and 0.5 MOA per click windage and elevation, fits a 1in Weaver or MIL-STD-1913 rail, measures 5.6 x 2.2 x 2.9 in and weighs 13.8 oz (391 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.
The reticle is a hologram rather than a reflected LED, so it stays usable through a smeared or partly blocked window, and EOTech project it at 200 m to minimise parallax. The 518 is not night vision compatible; the EOTech 558 is the same layout with night vision settings.
Any 1in Weaver or MIL-STD-1913 Picatinny rail. The side controls make it a natural partner for a flip-to-side magnifier such as the EOTech G33 with STS mount. EOTech calibrate the reticle's aiming points for .223 62 gr at 2,900 fps.
