Feature rich - Holosun HE507K-GR X2 1x Green Dot Reflex Sight

I just installed this on a Glock 40 and am very impressed with the features. The low profile takes a little getting used to but the sight is a good fit for the MOS model and is not obtrusive. I have previous experience with guide rod lasers and red dots. I like the green dot with the circle because the eye picks it up more easily and it can be very bright if you would like for daylight shooting.
This one is mounted with plate #5 but you have to remove the pins for it to sit flush. The one MOA dot does not obscure the aiming point for target shooting and the controls are easily adjustable.
