I've had three cans for maybe two months and there's no going back for me. Many existing rifles will stay the way they are, some will be chopped/threaded (where rifle balance will not be unduly upset), but most new additions going forward will be planned for suppressed use. Nice to mitigate recoil and blast at the same time, especially when shooting is an impromptu affair. There are decent 10-12oz .30cal cans out there now for $500-700.
