Maxwell Atchisson's automatic assault shotgun, dubbed the AA-12, delivers pure destruction to anything in its line of fire. The AA-12 can unload a 20-round drum of 12-gauge shotgun shells in under four seconds at a devastating 360-rounds-per-minute.
It's in a class all its own as it provides troops with an insane rate of fire with relatively low recoil.
"The versatility of that gun is frankly amazing," said John Roos from On-Target Solutions. "The absence of recoil means a light person, any military member, can fire that weapon and there's no trepidation when you're firing it. Sometimes a 12-gauge can be intimidating. This one looks intimidating, but it's a pussy cat when you fire it."
Anything within the 100-meter max effective range will be destroyed. If not, the AA-12 can still use less-than-lethal stun rounds to incapacitate hostiles. But if you absolutely need to get rid of whatever is in front of you, pop in a high explosive FRAG-12 round to make it like another automatic weapon we all know that fires explosive rounds.
The AA-12 may be the natural successor in a long line of terrifying shotguns, but the HAMMER is a proposed unmanned defense system which would have two of these bad boys attached on top of a remote-controlled ground drone.
