Atchisson Assault Shotgun # 9
Originally designed in 1972 and later perfected, this is something many probably only think exists in video games or movies. Even though it has been featured in movies, as demonstrated by Terry Cruz above in The Expendables, this gun is very real and is a force to be reckoned with in today’s military. A handheld, fully-automatic shotgun has practical applications in close quarters warfare, where combatants are only meters apart. The weapon also has the capability to fire a diverse type of shells given the flexibility of the shotgun cartridge.
The Atchisson Assault Shotgun can be used for clearing rooms full of adversaries, as well as providing dangerous cover fire for troops needing to move across dangerous territory. This weapon is lethal and portable, earning it a spot on the list.
