I have multiple of these. Love the sight overall. Run it on my house AR and my hog gun. Haven't done anything past 100 yards with it. But everything inside of 100 has been awesome. 25 yard pre-zero was spot on. Shake awake is a must have feature.

Shipping was SUPER fast!!! The sight was all that they said it should be. I was worried about the height of the unit but it was high enough for me to stay in a comfortable position, no need for a riser.
