Would also recommend Recknagel, they have the biggest choice:

Obviously, you have already ordered the Leupold, let me comment on the scope anyhow: 9 inch eye relief is a lot for a regular scope, however you will be surprised how fast you run out of eye relief on a double if you want to move the scope forward, due to its construction. The Aimpoint has unlimited eye relief, will also work at 3 feet distance if you look through the scope at an angle. As for 2.5x magnification: For precision shooting there is not much practical difference between 1x and 2.5x, however with 1x you have a major advantage: With 1x and a red-dot system, you can easily shoot with both eyes open - the outline of the scope blurs away and all you see is the red dot and your target, while you have full view of the surroundings. This way, you get on target extremely fast, especially when the target is moving. Since it is truly parallax-free at all distances, you will hit even with an incorrect mount. It's also surprisingly easy to shoot precisely at distance. Try it out some time when you run into it (at a gun show, for example), you might like it. First time I used it was truly a 'wow' moment.
