Depending on the feed mechanism you may need a stopper on the barrel. Never used an M-16, so I don't know what is needed there. But it can be done. If that is a smart thing to do in a war zone is another matter...
The M16 I used required a "blank firing device" attached to the muzzle to prevent gas from escaping thus providing enough back pressure to operate the eject mechanism. Semi or full automatic worked just fine.
