 In a production line, and it's just wild because you can shoot, you know, do an endurance test with it, and your red dot is still clear. Like, you don't have to wipe it. That's amazing. I love that.

Some of those optics companies put some pretty crazy coatings on the front, but you don't want to be messing with that, you know, hot.
