I'm using a bit of a different approach in building this, which will probably make things a bit easier and accurate. Normally, the split side plates would have been glued together, then glued to the bottom plate of the receiver, but when doing so, you could get a slightly different length for each plate, so that when you finally glue everything together you will either have one side, maybe, a mm or so, shorter than the other, due to sanding/filing/gluing errors which would throw off the alignment of the entire prop. But because the real weapon has rectangular plates around the place the ammo enters, and the links are expended on the other side, this will provide a great reinforcement for the two plate halves. Each side plate half is secured to the bottom receiver plate using brass 3/16 rod as a guide.
Securing the rear grip works almost exactly like on the real weapon. The buttstock (only partially printed, slides down into the back and is held by a screw at the bottom, which is partially hidden by the grip. The real buttstock latches into place at the bottom, but I decided to go the simpler and more rugged approach.
The only parts that are post-processed and sanded, for now, are the items that interact with each other. I'm just making sure that when things are designed, that they actually fit in the real world when printed. So far, so good.
The gas tube is also reinforced with a 1/2 inch copper plumbing pipe.
