Not publicly, so far as I know.

Any time someone purchases a gun from a store, or from most dealers at gun-shows, a background check gets run. This, + paperwork and records residing with individual sellers are your only real sources of data, neither of which are public.

The concept of a national gun registry has been debated hotly for quite a while, but that would definitely not be public if it existed.

These aren't clear either. Is that $1000 At Guns R' Us a rifle, or bulk ammo? Is that $25,000 at Guns, Fishing and Other Stuff a rifle with fancy inlay or a new fishing boat.
