Great red dot! - Holosun HS407C X2 1x 0.63x0.91mm Reflex Red Dot Sight

I have this and also the 507c. I don't think I can go back to a red dot that you have to turn on and off. The shake awake has never failed and it's great not having to think about turning the red dot on and off. The red dot itself is a nice size at 2 moa and I can pick it up quickly as it co-witness with my front site. The solar panel adds a bit of security to the battery which on its own lasts a long time. Fits on a standard rmr mount which I think it's harder to find a slide that doesn't have this built in! This is great for a handgun but I prefer the round circle or 507c which has both reticles on my ARs.
