EOTech 512.A65 Tactical HOLOgraphic Weapon Sight Review


The EOTech 512 A65 Holographic Weapon Sight is the perfect non-magnifying sight for short range shooters. These Red Dot Sights from EOTech are perfect for shooters that want the best in CQB speed and versatility, without the need for night vision compatibility. A revolutionary weapon sighting system, the EOTech 512 A65 Holographic Firearm Sight enhances target acquisition, improves accuracy, and provides more control over your shooting environment. The EOTech 512 A65 1x Holographic Red Dot Sight fills the needs of all shooters, from the novice to the most advanced professional, ideal for field of view shooting. Easily linking to any Weaver or Picatinny standard rail, you can make good use of the EO-Tech 512-A65 65 MOA Circle-Dot Holographic Sight on all of your favorite firearms.


When it comes to rail-mounted, quick-target acquisition weapon sights, Trijicon brand sights are possibly the very best option on the market.  The Trijicon “ACOG” series has become the most sought after weapon sights used by the more notorious and reputable Military and Law Enforcement branches such as Navy SEALS, Marine SOCOM Units, SWAT and various other divisions.  The ACOG weapon sights have successfully bridged the gap between 1x magnified Red-Dot sights and traditional 6x-10x magnified riflescopes.  By utilizing the middle ground at 4x magnification, the ACOG employs a crosshair reticle with illuminated options and red / green color to allow for both night and day operation.  Although Trijicon ACOG’s are priced somewhat high when compared to the alternative brands like Aimpoint or EOTech, the performance and reliability the Trijicon ACOG offers goes way beyond the capabilities and functionality of the other brands.

The History of EOTech

In 1972, the Michigan State Legislature established an independent, non-profit research institute, Willow Runs Laboratories. It was later renamed Environmental Research Institute of Michigan (ERIM).

Two decades later, in 1993, ERIM formed Michigan Development Corporation (MDC) to commercialize ERIM technology and create spin-off companies.

In 1995, MDC created EOTech as a wholly-owned subsidiary of ERIM.
