I had the delta point, and sold it. It was good but I just didn't like it. mind you it was on a pistol. The dot is triangular and it reflects off both glass surfaces so you see double at times, which bothered the heck out of me. It is motion activated, and someties you have to shake the gun a little to light the dot. Minor issues for some but for me enough to let it go. The nicest thing about the deltapoint is the kit it comes with allowing the user to install on most handguns. on a handgun it takes too long to aquire the dot, which is a huge impedence in my opinion, you have to almost be right on target before the dot becomes visible. I believe an aimpoint t or H is a far superior product
