Adjustable Picatinny Rail (APR) Concept

I bought a red dot sight a couple months ago but didn't get to try it out until a month ago. Only after mounting it and doing some test fires did I realize that the red dot will not line up with the ball's trajectory. The sight can't be adjusted down enough because the drop of the ball is too great. I've been told that dot sights aren't meant for exact target acquisition but instead for eye-balling. Personally, no one needs to spend money on something to eye-ball and I didn't want to have a brand new sight just laying around doing nothing. So I got the idea for an angled rail. It couldn't be a fixed rail because not everybody's setup is the same. So it would have to be adjustable. I'm no machinist and wouldn't have the faintest idea of how to make one but I am pretty good with computers, so I taught myself how to model in 3D. After playing around some, this is what I came up with. It's just an idea right now and does not represent the finished product. I still need to double check the amount of angle needed and make sure that it's well within being adjusted to. The pins are just there to represent thumb screws and to show the concept of how it works. It's not shown in the video, but 3 small set screws, similar to that of the SpecOps rail, would secure the APR to the gun. You just remove the top rail to gain access to the set screws. As you can see, it pivots off of one pin that is fixed and the other is infinitely adjustable from 0 to (need to double check still) degrees. The top is a picatinny rail modeled after the Special Ops flat top rail and the bottom is the 3/8 dovetail. It should be around 4-5.5 cm high when finished and will also serve well as a riser mount. The top rail has two curved slots in the metal and the pin just slides through them. If you tightened the screws onto the bottom rail, it would prevent the top rail from moving as well. With this, you would be able to get the red dot really close to where you are aiming and then fine tune using windage and elevation on the sight itself. Once I get the details worked out, I'm gonna have it made unless I hear of a better design. EDIT: There's a working prototype!
