What is the difference between these two red dots? Because the reticle is the same.
Main difference: type of emitter
The key difference between Osight K and Osight SE 6 MOA is the position of the emitter. Osight K uses open emitter. Osight SE uses enclosed emitter.
What is emitter you ask? Emitter is something that you do not necessarily know about much. To put it short, you need to know two things:
#1 Emitter is basically the source of the red dot that you see when you aim. It is the device that projects the dot to the glass.
#2 Red dots use one of these two types of emitters: open emitter and enclosed emitter.
If the emitter is open, you can make it dirty or damage it, if you are handling the red dot roughly. As a result, the dot can become blurred.
If the emitter is closed, it is protected by glass. The red dot then however becomes more robust, because it needs to have glass from the front and from the rear – to protect the emitter, and to have a glass where to project the red dot.
