Call Milehighshooting and ask when they will have their LR-17's in stock. They should be stocking US Optics scopes very soon and they are awesome to deal with. Though I don't have any personal experience with him, I hear that Lazy21 is also a very good resource for US Optics scopes.
If the in-stock options don't work for you, call US Optics on Monday and ask. They are really good people and I'm sure they would welcome your questions.
