They introduced their first-generation holographic weapon sight at the 1996 SHOT Show, which won the Optic of the Year Award from the Shooting Industry Academy of Excellence.

[3][4][5] The sights are designed to be mounted on small arms via a MIL-STD-1913 Picatinny or Weaver rail, and powered by either AA, N or CR123 size batteries for up to 1,100 hours of runtime.

In 2015, the U.S. government sued EOTech's former parent company, L-3, for civil fraud, accusing it of covering up defects in the sights it knew about as early as 2006.

[9][10] In 2018, EOTECH was awarded a $26.3 million five-year contract from the U.S. Special Operations Command (USSOCOM) to provide close-quarters sights and clip-on magnifiers for the Miniature Aiming System–Day Optics suite.

[11] In 2020, EOTECH officially separated from L-3 Technologies and was purchased by Project Echo Holdings dba American Holoptics,[12] a subsidiary of Koucar Management.

The sight's parallax due to eye movement is the size of the optical window at close range and diminishes to zero at the set distance.

Lasers use more power and more complex driving electronics than an LED of an equivalent brightness,[citation needed] reducing the amount of time a holographic sight can run on a single set of batteries.
