A new modular assault rifle developed by Izhmash to replace the AK-74M and AK-10x series. Chambered in 5.45x39mm, 5.56x45mm NATO, 7.62x39mm, and 7.62x51mm NATO. The prototype was called the AK-200. It's called the AK12 now because it's supposed to enter production in 2012. It may replace or supplement the AK-74M as the standard Russian service rifle, since the Russian government can't afford to buy AN-94s for everybody (except certain Spetsnaz groups) at the moment. The 60-round 5.45x39mm magazine designed for the AK-12 will also work in the AK-74, RPK-74, AEK-971, and AN-94, as all of these guns share the same magazine design.

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.
I really hope they replace the AK-47 with the AK-12 and AN-94 in the next Call of Duty since only seriously impoverished terrorists use AK-47s these days.

Semi-automatic 12 gauge shotgun built on the AK-47 design. Slightly modified to permit larger shell size, this excellent offering from Izmash Arsenal in Russia accepts box magazines holding between four and ten rounds at present. Larger capacities are rumored to exist. The stock weapon uses an adjustable gas system to permit it to cycle low-brass "target" loads or full-sized shells. A number of short-barrel highly customized versions are availabe and very attractive as home-defense and offensive weapons.
"What in Hell is that?"

"AK-12."

"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!"

"Yes, officer."

"Well, I got no reason to hold you. Have a good night."

What Bush was looking for when he invaded Iraq, truly a high performance weapon of mass destruction. This lil' beauty is an authentic Russian made AK-47, but has been made to shoot 12-gauge shotgun shells instead...6 of them as fast as you can pull the trigger! Manufactured by Saiga.

Private: Sir, requesting permission to speak, sir.
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!

What people who don't know guns would call a Saiga 12.

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.
Called an "AK-12" by the uneducated, Saiga 12's are classified as an assault weapons in California.
