Some really basic types of hop up units (fixed ones) have a slot cut in the inner barrel, and use various sizes and thicknesses of O-rings to generate hop up. Minigun comes to mind, as well as 40mm shot shells, the O-ring is positioned to do what a hop up rubber does. Mind you, sealing the breech with the nozzle will give you another issue to sort out, but at least you now know how to put a basic backspin on a BB.
