Re: NFA transfers
Another caveat. ANYONE can sell a registered NFA firearm that is also a C&R (example: a WWII Thompson SMG) to a C&R FFL holder in another state on a Form 4 and ship/take the gun directly to him/her without going through any SOT dealer. If the NFA firearm is not a C&R or if the buyer is not a C&R licensee, the gun must go through a class III dealer in the transferee's (buyer's) state. It is not necessary to go through a class III dealer in the transferor's (seller's) state.
Note that C&R status can apply only to complete firearms (i.e., guns), not to suppressors, full auto parts (DIAS, M2 Kit), or other NFA "firearms" that are not actual guns.
