If my Dream were to come true, the action would the the short-throw piston/bar set-up that Heckler & Koch conjured up to further evolve the AR combat capabilites.

'Course they've already got their own iteration with the HK416, a favorite of the USSOCOM grunts from what I read/hear.

From the picture above, it’s a plain old gas tube.
