Getting my hands on the smaller Eotech over the weekend, we thought we would take some pictures to compare them in size. A lot of people ask us about this and we had no chance to do this before now. For those trying to decide which they want, this may help. The Eotech is compact, but still no where near as small trim and light as the T-1. We have often given our opinion on the eotech and how we feel it can not be trusted based on the many, many instances of its failures in front of us or models we owned in the past. But there are always gonna be those who want them because they see SEAL or some such using them. Keep in mind even a lot of guys in SOCOM DO not care and will use what is handed to them. But, the point is, here is a comparison for those who want to see a good side by side. You can do you own research on which one you think will work best for you otherwise. You can find out thoughts and feelings on the trustworthiness of the Eotech in other posts.
