From Fox News:
“Two federal officials told the Associated Press that Alexis had an AR-15 assault rifle, a shotgun and a handgun that he took from a police officer at the scene.”
The 12ga MKA is on an AR platform:

Sweet cherry pie!
So, time to disarm the military?
I own one of these shotguns. The layout and operating controls are indeed similar to the AR-15, with the exception of a bolt mounted operating handle on the right side, but the internal mechanics and operating system are more akin to to a Remington 1100 semi auto shotgun than an AR-15. I have two 10 round mags and two 5 round mags and the thing is as smooth as butter and really puts pellets down range FAST!!
