Circuits nailed it for sole proprietor FFLs.

If you own an incorporated business - even a single member LLC, and the business has the FFL, then you are no different than some guy off the street when it comes to the transfer process. Your name may be on the license as a responsible party, but the law makes you run a NICS check on yourself - something you wouldn't need to do as an individual FFL. Funny that you can check the gun out of inventory at will, but you can't transfer permanent possession without a NICS.

I guy could go positively schizo filling out the 4473.
