M. T. Sounds as though a laser is what your looking for.
A built in cooking system could also be installed. Now is the laser would melt a Hippo with one blast then it would soon be needed for elk and deer as well. Maybe the folks a Winchester could get to work on this right away. It would have to have an artificial recoil unit so it could be set to knock peoples eyes crossed or the macho feeling wouln't be there.
