Quick correction to what I wrote earlier, I have used the Burris quick release scope rings, not the Leupold. Using the quick detach Burris rings on the top of my AR-15 I have taken the scope off and put it back on enough times to see that it will shoot almost exactly the same as it did before I took it off. I really like system, I'll be picking up a regular weaver mount and the quick release rings tonight if it's on the shelf.
