I used a Weaver Quik Point years ago and I can tell you it works great on flying targets. I ran many a 25 at skeet and trap warming up for waterfowl season. The dot and the bird are in the same focal plane, so instead of using the traditional sight picture you just concentrated on putting the red dot where you wanted the pattern to go. I stopped using it because I had continual problems with the mount, it was heavy, and it was bulky, and it used natural light, not because it didn't work well when light conditions were good. I am seriously considering a Speed Bead, except the cost is putting me off since I am without a job at present.
You do not have to worry about fit, cheek weld, keep head down, nothing, except if you can see the dot and it is where you want it, and you calculated the lead correctly, you will hit the target. It's different. I even shot some targets using an occluded sight. You block the sight tube, and your normal dominant eye sees only the dot, and your other eye sees the target, and your brain puts them together and you still hit the target. I got a 23 at skeet and a 24 at trap doing that and amazed the heck out of some people, including me.
