Apparently some hicks also call the Saiga-12, Vepr-12, and KS-K (Karabin Spetsialny Kalashnikova- the military version of the Saiga-12) "AK-12s" because they're chambered for 12 gauge shotshells.
"You pay the extra $200 for the short-barrel on that? It looks vicious! And you've got a stack of 10-round clips loaded with buckshot! Is that body-armor you're wearing? You're better armed than me and my partner!"

Captain: Permission granted private.
Private: Sir, our latest intelligence report indicates that there are more than 60,000 troops headed our direction. They are armed with fully automatic weapons and RPGs. There are also 50 Bradley tanks with them. I am sure you are well aware that we have sustained heavy casualties in the past two weeks and morale is at an all time low. Further more, our support is more than 12 days away.
Captain: Private, I give you a direct order to send up multiple flares so that the enemy can pinpoint our exact location.
Private: Sir, are you fuckin' nuts?
Captain: We have one AK-12 private, we are about to take those gheymos for a Polish bike ride that they will never forget!
A Saiga 12 is a Russian designed Kalashnikov-pattern semi-automatic combat shotgun. It has excellent reliability due to it's AK style design and is manufactured by Izhmash in Russia. Pretty awesome, really.
