    Having looked at other chassis thingies, it is actually reasonably priced. I never really got into the chassis game so I never knew they were that expensive.

    With this being a new design, I'm surprised the stock doesn't fold to the right. That way the stock isn't sticking out one way and the bolt on the other. Just heps streamline it more for the pack or case. I figured everyone was going this route from now on. Won't lie... MPA isn't known for their precision rifles. Interesting they're going that route, but maybe not quite there yet for someone that wants to 'buy once.' I've never used an MPA firearm though.
