The folks at Franklin Armory are now selling a firearm called the CSW.  The gun uses many of the same bits and pieces of a standard AR-15, but does not have a pistol grip or shoulder stock.  Instead, the firearm uses a spade grip, similar to what can be found on the M2 machine gun.  Independent triggers are located on each grip.

According to Franklin Armory, the gun is not classified as an “assault weapon” under any known law.  Consequently, it legally eliminates the need for a Bullet Button in California.

A kit will also be available for shooters to convert an AR-15 to the CSW.

Thanks to Cymond for the tip.
