Red dot brightness inconsistent - Gideon Optics Rock Red Dot Reflex Sights

After opening the box, the first thing I did was turn it on. Honestly, I was automatically disappointed. I purchased this optic to mount on a 45 degree offset to run with my LPVO. I wanted the 65mm circle around the red dot to get on target faster. Looking through the sight, there was a drastic difference between the brightness at the top of the 65mm circle. The top was extremely bright while the bottom was noticeably dimmer. I took the optic out to daylight and the issue worsened. Outdoors the bottom of the 65mm circle was nonexistent. Thankfully Optics Planet is handling the return.
