I am skeptical for the reasons given and that Caracal has already offered something very similar and even after they were freshly introduced and before the recall I didn't see or hear that the sights were so impressive that people wanted them on other guns. That said it was a short time and limited amount of testing/review and numbers of users. I will give them a chance and would like to try them out to see how they do with my aging eyes that don't get the front sight clearly focused. I wonder if they work better or worse for young eyes or aging,close range or far and how precise of hits/groups can be reasonably achieved at similar speed.
Plenty of hype in the video with some questionable claims but the proof is in the results.
Holster design and selection will be a real consideration for getting things going even if interest is there.
