The subject of thermal drift and parallax has been a hot topic lately. In simplest terms, thermal drift is what happens when  the sight’s point of aim differs from its point of impact when subjected to a temperature variant.  Parallax is essentially an optical illusion that presents itself as the apparent movement of the reticle in relation to the target.

Our readers will remember Dave Merrill’s article Parallax Free, Isn’t, from June of 2016.  As Dave said, “Just knowing the nature of what parallax is and how it works I will be legitimately surprised if anyone releases a useful truly parallax free red dot.”

Regarding these recent events, EOTech recently made the statement, “By now you have probably heard many things about thermal drift and parallax as it relates to EOTECH HWS. Truth is, all optics experience both of these to some extent. We believe that an educated shooter is a better shooter, and recognize that this information coming directly from EOTECH may be considered bias.”

Garand Thumb recently posted what he describes as his own unsolicited and unbiased video review about these issues on youtube.  He rates EOTech sights and how they measure up to competitors.  The Green Eye Tactical study about parallax that Thumb mentions in the video can be found here.

Also in current EOTech news, they are continuing their Sight-In Rebate until November 30.

    Good video review, and plenty of good points to be made. EO Tech is far and away my favorite reticle, and I love the large size of the sight window. HOWEVER, I cannot in good conscience purchase a critical piece of equipment from a company who had to be subjected to a federal lawsuit to rectify the issues with their products. I returned all three of my EO Tech sights to the company for a refund, and purchased Aim Point and Trijicon sights as replacements. There are too many excellent options out there to stick with EO Tech, in my opinion.
