The EOTech 512 holographic sight (EOTech part no. 512.A65) is a holographic sight from EOTech that EOTech calls the most popular HWS in its lineup. It uses a 68 MOA ring with a 1 MOA dot and runs on easy-to-find AA batteries. The 512 is the choice for shooters who do not need night-vision compatibility and want fast target acquisition, rugged construction and a sight made in the USA. EOTech notes the HWS line is the Close Combat Optic of choice for USSOCOM, and the sight carries a 10-year warranty. It suits an AR, a carbine or a home-defense shotgun.
