As I read it the law only applies to non-serialized 80% firearms. Law requires a serial number on an 80% firearm but it doesn't say you can't have a serial number on an 80% firearm. So if a 80% part manufacturer put a serial number on it prior to purchase then it would seem to not apply. So if you buy a chunk of steel or aluminum you plan to make into a firearm then engrave a serial number first and you would seem to be fine? Gotta double check the text of the law but this would seem to be a workaround.
This is exactly how it works and what I said earlier. IT IS LEGAL to get these and assemble them AS LONG AS YOU SERIALIZE/REGISTER THEM. And it does not say who puts it on. WORDS MATTER.
SECTION 3. Chapter 134, Hawaii Revised Statutes, is amended by adding a new section to part I to be appropriately designated and to read as follows:
"§134- Manufacturing, purchasing, or obtaining firearm parts to assemble a firearm having no serial number; penalty. (a) A person who is not licensed to manufacture a firearm under section 134-31, or who is not a dealer licensed by the United States Department of Justice, shall not, for the purpose of assembling a firearm (if that is not your purpose for purchase, then it's not against the law)
, purchase, produce with a three-dimensional printer, or otherwise obtain separately, or as part of a kit:
(1) A firearm receiver that is not imprinted with a serial number registered with a federally licensed manufacturer;
(2) A firearm receiver that has not been provided a serial number that may be registered in accordance with section 134-3(c)
; or(This is where you put your own serial number in the event you ever change your mind on assembling)
(3) Any combination of parts from which a firearm having no serial number may be readily assembled; provided that the parts do not have the capacity to function as a firearm unless assembled.
(b) Violation of this section is a class C felony."
SECTION 4. Section 134-1, Hawaii Revised Statutes, is amended by adding two new definitions to be appropriately inserted and to read as follows:
""Assembly" means the fabrication of a firearm or the fitting together of component parts to construct a firearm.
"Firearm receiver" means the part of a firearm that provides housing for the firearm's internal components, including a hammer, bolt, breechblock, action, or firing mechanism. "Firearm receiver" includes any object or part that is not a firearm frame or receiver in finished form but that is designed or intended to be used for that purpose and may readily be made into a firearm frame or receiver through milling or other means."
§134-2 Permits to acquire. (a) No person shall acquire the ownership of a firearm (80% IS NOT A FIREARM AND NEVER WAS and is incapable of being used as such)
, whether usable or unusable, serviceable or unserviceable, modern or antique, registered under prior law or by a prior owner or unregistered, either by purchase, gift, inheritance, bequest, or in any other manner,
