Are full auto fire control groups legal?
A commercial website that specializes in various gun supplies that I frequent has often carried full auto control groups and lower recievers with full auto control groups (on guns where the upper reciever is considered the firearm). I was baffled by this as I had always thought it illegal to sell anything which would make a firearm full auto. I was wondering if any of you could tell me whether or not it is legal to sell something like this online. Even if you had no intentions of modifying or building a gun with these parts, wouldn't someone have to have the Class III firearms license to purchase something like this?
