If I got one of the PackRifles I'd want to McGuiver some sort of case to carry it in. My pack gets pretty beat up every day while hunting - used as a seat or a back rest or just bumping into rocks. I'd never feel comfortable carrying the PR broken down strapped to the outside of my pack. I can envision getting everything inside of a fairly small diameter tube except the grip. Maybe cut a slot in the tube for that? I'd have to get that figured out before I'd want to carry it.
