There really are versions of AR shotguns on the market and they are in great demand.

This from "Guns America" website:

"If there is a must have product at SHOT 2012, it is the Akdal MKA 1919 semi-auto shotgun, exclusively imported in the US by RAAC. It looks like an AR-15, but it is a super-sized version made for 12 gauge shotgun shells in both the 2 3/4″ and 3″ size."

If you search by "AR shotgun", you'll find a LOT of info.

Now, was that what was used in many, if any of the articles written by ignorant reporters? Doubtful.

There aren't that many of them out there yet.

with a few 'minor' adjustments, you can turn one gun into 5 guns
