When you really look at the way the rifle is built it is really pretty simple. It's not a huge departure from anything that already exists, and like any other rifle it has it's inherent issues. BUT, I think the real problem is tooling. To tool up to make something like this would require a ton of funding and alot of one off tooling. It absolutely could be done with enough time and effort of course. The welding on the receivers is really very, very well done. It looks like it would take alot of time to put one of these things together.
