Great product at very reasonable price ....

My shooting targets improved immediately after installing a Holosun HE510C Green Dot Open Reflex Sight with a HM3X. The green dot is bright and shooting in day light doesn't reduce the bright green dot. I'm looking at eventually installing another Holosun on one of my other firearm.
