So, as usual, I was looking at fun porn and saw someone mention these. I had heard the name before, and the concept IMMEDIATELY struck me as superior to standard iron sights. Standard irons you are lining the top of a post in a circle, and while doable win great accuracy, that takes not only time but a hell of a lot of experience. The diamond head design looks to be unbelievable fast, I believe a study of the human mind showed that it's much quicker to line up straight lines such as a box within a box then curved, such as a circle in a circle or, look at that, a post within a circle. I really, REALLY like those sights. Does anyone have any feedback on them? Are they as good as I'm thinking they are? Are they high quality, and what is the companies customer service like? Thanks!
