This is NOT an EOTech 518. It only takes the design style of it. It’s just a normal red dot sight you find on Amazon. No special features, it’s just a plain red dot sight. It has a hood made of metal. Holds zero alright. At about 180 rounds of 233/556 I’d say is when the zero starts to drift and has to be rezeroed. That’s not accounting bumping this thing to random things. May fair better in other platforms.

Comes with case and manual. No batteries.
