Excellent value - Holosun HE508T-GR-V2 Green Dot Sight

I recently put this on a shadow systems mr920 and I am very impressed with the over all build and materials. Having three reticle choices is fun but the single dot is most applicable for me. The auto brightness feature is a major plus and it works well. I will say the glass is clear enough to see the fixed sights but there does seem to be a distortion which, if not using the optic, forces me to aim lower than previously. Bang for the buck, this seems like it was a good choice.
