The Brazilian Uru SMG: A Study in Simplicity

The Uru, named for a tropical bird, is a Brazilian 9mm submachine gun made from 1977 until 1985 and used by Brazilian military and police forces. What makes it interesting is the designer’s focus on simplicity – the gun has just 17 parts, and basically no screws or pins (except the bolt holding the pistol grip on). The trigger mechanism and drop safety are quite interesting to see!
