You want to hunt with a machine gun, or are you referring to an AR-15? Either way, it depends on where you live. Check the yellow pages.

Yes, it is, as it is already registered and tax stamped as an SBR.
The AR-15 was created by a design team led by Eugene Stoner. Initially, the AR-15 was intended to be a companion rifle to the AR-10; the AR-10 was intended to replace the M1 Garand while the AR-15 was intended to replace the M1, M2, and M3 carbines.
The AR 15 is a rifle, not a caliber. the .223 is a caliber. Usually the AR-15 is made in caliber .223.
