Green dot works great with my astigmatism. Auto brightness works well so far. I still wish it was still a little brighter than what the auto-brightness feature makes it.

It can also be cycled between circular dot reticle, dot and circle. The 32 moa circle is my preferred setting.

It appears that perhaps the front of the optic was broken or damaged and someone attempted to glue it to fix it. Distracting glare on the inner moa even at half brightness.

The holosun he507k-gr x2 / hs507k x2 is an exceptional reflex sight. It offers unmatched versatility, durability, and performance.

Red dot reticle is far too high and out of view unless i point the * downward. My dot randomly get dimmer or brighter without me touching anything usually gets dimmer.

Hope they can straighten this out. Their rma process is trash. Completely unacceptable. No response whatsoever.

This unit was replaced by the service dept with a 507k at my choosing. The manufacturer claims battery life is “up to 50k hrs’. That equals 2073 days or 5.
