This is a really cool idea. I think that you may run into packaging issues in the receiver of the AR. It's going to be pretty narrow inside there. If you use the 7.62x51mm case that the AR supposedly uses, then your mechanism will need to be really compact yet sturdy. I may be missing something, so more detailed drawings may help. I have an idea that may work. Basically it's a bolt carrier that sits above the trigger area. A motor drives the bolt carrier back to where it rides over the shell casings that sit in the magazine. The carrier strips off the top casing and drives it forward. As the shell and carrier move forward the shell rides along a ramp that pushes the nose of the casing outwards towards the ejection port. The bolt carrier has a slot cut in it for the ramp to ride in. The bolt carrier, having ejected the shell, then returns to its forward resting position, ready to eject the next shell. I'll try to produce some drawings to better explain this. Hope this is constructive.
