I have a Delta Point Pro on two compact SBR's and have not yet found a better one got this purpose. One is mounted on an 8" 300 BLK and the other is on a 6" 9mm AR. While mot designed for long range use this optic is Hard to beat on targets inside 200m. This thing is quick, dead on, and never loses zero unlike other brands I've tried. This is my go yo optic for anything inside 300m and can't wait to get one mounted on a pistol. The window is much more generous than Trijicon and much higher quality than Vortex. I will be getting a couple more of these because while it's always good to have a set of back up irons they will never match up to these in speed and accuracy. The auto on/off feature sets it apart as well. You can never go wrong with Leupold!
