I would just like to add another person to the ever growing list of people who think that the frame is great. I was able to shoot one on the tech-at-my-field's gun. He was at WC installing them with Centerflag. It was amazing. I have an angel and could shoot the uprising even faster, because the trigger was a little heavier and I could get in a better rythm. I was incredibly impressed. It's a great enclosed system, and I now appreciate the time they must have spent getting it to work they way they did. Great Job CF!!!!!
