A reader email in a scan of McDonnell Douglas advertising material that promoted the McDonnell Douglas Scorpion. The scorpion was one of the entries in the US Army’s Multi-Purpose Individual Munition (MPIM) competition in the 80s. This (in my opinion) ridiculous weapon weighed more than the gun it was attached to!
It was obviously not designed by a rifleman.
