David of Very Traumatic sent this to us. He decided to test the Eotech recall on his own. He shot his AR with an Eotech and then submerged the Eotech in dry ice to get the Eotech cold enough and test if there is a shift.

Cut to the chase, there is POI shift. David does talk about the variables such as removing the optic and remounting as well as the glass fogging up.

One aspect I am curious to know is what happens to the rifle when frozen. Will temperature affect POI of the rifle as well?
