personally i cant use the sight because of the red glass that the red dot is shown on. the whole point of red dot sights and reflex sights is quick target acquisition from a large and clear sight picture. red dot on red tinted glass is clear as mud, if you add any color to the glass it should be a yellow/green tint like irl. it gives better contrast to the red dot and enhances visibility in low light conditions. perhaps giving us options for the dot and glass colors so we can tweak them to our liking?
