Lauderdale, FL 33314 954-581-2144 Please note the red dot sights work by reflecting light from a light emitting diode off a mirror and back to your eye, in order for this to work, the unit must be slightly angled for the light to reflect off the mirror. Therefore, the mirror located in the ocular lense is tilted to allow for the reflection.
