== Miniguns ==

One unusual type of gun is a minigun. Despite what you would think from the name, a minigun is the biggest of all small-arms. A minigun has multiple barrels which are driven by a loud electric motor. This allows it to have a very high rate of fire, and is a major difference from the systems of operation described at the top of the article.

Miniguns are commonly seen in the movies, notable examples being [[Terminator 2]] and [[Predator]], where miniguns can be seen exploding multiple police cars or cutting down whole areas of forest. In reality miniguns probably cannot actually cut down trees, and standard 7.62mm ball ammunition would not cause a car to explode, although a [[tracer]] round might if it hit the gas tank.

Until recently, guns were manufactured in factories to exacting specifications and careful engineering.  If a gun was not carefully made, it could explode in the user's hand and would be unsafe.  With the advent of 3D printers and strong composite plastics, hand guns can be made which would be difficult to detect by traditional metal detectors.<ref>{{cite news|url=http://www.wired.com/2014/05/3d-printed-guns/|title=How 3-D Printed Guns Evolved Into Serious Weapons in Just One Year|work=Wired Magazine|date=May 15, 2014|accessdate=April 3, 2016}}</ref><ref>{{cite news|url=http://www.npr.org/sections/alltechconsidered/2013/11/14/245078880/plastic-guns-made-with-3-d-printers-pose-new-security-concerns|title=Plastic Guns Made With 3-D Printers Pose New Security Concerns|work=NPR|date=November 14, 2013|accessdate=April 3, 2016}}</ref>
