That is my point. The FCC box is not innovative. It's just copying, unless there is some kind of performance upgrade I'm missing. I agree there is a big lack of PTW aftermarket parts and I would love to see items that raised the bar even a little. i.e. the Race trigger, Mini Mosfet etc. How about CNC'd lower receivers that were under $200 . The gearbox seems like a huge amount of effort without a real market need/demand.
