For all intents and purposes, the inner barrel is actually "fixed" to the midframe and never moves.

As the slide moves forward, when it gets to the point where it needs to start pushing the outer barrel forward, the compensator won't be there. It'll be floating about 5mm in front of the slide. Even if the slide were able to slam against the compensator, all it would end up doing is pulling the inner barrel, and again, the inner barrel isn't connected to the outer barrel. The outer barrel is free moving, and the problem right now is that the outer barrel isn't moving forward anymore. It needs a way to be pulled or pushed back forward. That's why an outer barrel mounted compensator (or ring) would work.

Ohhhhh! Now I get it. Need more physics in the brain.
