He508t-x2 green dot sight - Holosun HE508T-GR-X2 1x 2 MOA Dot Green Dot Sights

I just received and mounted the 508T green dot sight. It was very simple to zero it 15 yards. It enabled me to tighen up my shot groups. With the new optic, my shot groups are tighter at 15 yards than they were at 7 yards with iron sights. The shake awake feature is great for self-defense purposes, and the battery won't go dead because I forgot to turn it off. The only downside I have found is that the green dot is not as round or crisp as it should be on a 400 dollar optic.
