Two variants exist: diode at 4 o'clock and diode at 6 o'clock. avoid the later. - Bushnell AR Optics 1x25mm TRS-25 HiRise, 3 MOA Red Dot Sight

I have had and loved a number of TRS-25's over the years, as have many of my friends.
The latest one I purchased was different from all the previous ones regarding diode location. This latest one has the diode located at the 6 o'clock position, while all the others had it at the 4 o'clock position.
In the sights with diode at 6 o'clock the dot will NOT be visible in the whole window. In the top 1/4 of the window, the dot simply disappears. There are numerous threads on the net about this issue you can check. Bushnell does not acknowledge this as being an issue and they are not repairing or replacing these sights. I am disappointed and will not purchase a Bushnell product again.
