I was looking to upgrade my sight and Paul told me to try this Armor Tech HD. All I can say is it's a great sight. Made soild and the pins capture the light perfect. I like how it was so easy to switch from a right handed sight to a leftg one. the adjustments and third access is so easy to do. The price wasn't bad either. I bought the .19 thousnad pins. And compared to other .19 thousand pins these are true .19.
