Why has no one tried remaking this masterpiece? Most of the limitations it had were because of the manufacturing tech of the time, rather than a real issue with the concept. Another thing about this set up is because of the position of the magtubes it could be redesigned around a shorter 3 capacity per tube (6 total) that would end up about the size of an AR-15 magazine without any of the reliability issues that typically come from being box fed given the replaceable mag is the same configuration as a standard tube magazine and would slot in like a P90 mag. It could also run the long tube as a fixed option that can be removed, making the platform extremely versatile. The KSG tries but its more awkward to load and it does not have the alternating load option the Neostead does.
