  • My 503 g does fit with only 2 holes. Not all 4 line up with the aimpoint t1 t2 mounts. Is that right or is mine just weird. I keep reading they are the same but not all 4 holes. It will fit with 2 screws but saying it the same footprint and fits leaves a little to be explained.

    • All 4 screw holes on the dot’s mounting surface should align with the holes on the mount. Did you compare the photo of the footprint in this article with the footprint of your 503G – are the holes in the exact same place? If not, it might be a factory defect.
