Wyo. Stat. § 6-8-404 (2026)

accessories, ammunition and antique firearms manufactured in
Wyoming; exceptions.

     (a) A personal firearm, a firearm accessory or ammunition
that is manufactured commercially or privately in Wyoming and
that remains exclusively within the borders of Wyoming is not
subject to federal law, federal taxation or federal regulation,
including registration, under the authority of the United States
congress to regulate interstate commerce. It is declared by the
Wyoming legislature that those items have not traveled in
interstate commerce. This section applies to a firearm, a
firearm accessory or ammunition that is manufactured in Wyoming
from basic materials and that can be manufactured without the
inclusion of any significant parts imported from another state
or foreign country. Generic and insignificant parts that have
other manufacturing or consumer product applications are not
firearms, firearms accessories or ammunition, and their
importation into Wyoming and incorporation into a firearm,
firearm accessory or ammunition manufactured in Wyoming does not
subject the firearm, firearm accessory or ammunition to federal
regulation. It is declared by the Wyoming legislature that
basic industrial materials, such as, but not limited to,
polymers, unmachined metal, ferrous or nonferrous, bar stock,
ingots or forgings and unshaped wood, are not firearms, firearms
accessories or ammunition and are not subject to congressional
authority to regulate firearms, firearms accessories and
ammunition under interstate commerce as if they were actually
firearms, firearms accessories or ammunition. The authority of
the United States congress to regulate interstate commerce in
basic materials does not include authority to regulate firearms,
firearm accessories and ammunition made within Wyoming borders
from those materials. Firearms accessories that are imported
into Wyoming from another state and that are subject to federal
regulation as being in interstate commerce do not subject a
firearm to federal regulation under interstate commerce because
the firearm accessory is attached to or used in conjunction with
a firearm in Wyoming.

     (b) A firearm manufactured or sold in Wyoming under this
act shall have the words, "made in Wyoming" clearly stamped,
inscribed or otherwise marked on a central part of the firearm,
such as the receiver or frame.
     (c)   To possess a firearm covered by this section a person
shall:

          (i) Not have been convicted of any felony in any
state, territory or other jurisdiction of the United States.
This paragraph shall not apply to antique firearms;

          (ii) Not currently be adjudicated to be legally
incompetent; and

          (iii)     Not have been committed to a mental
institution.

     (d)   To purchase a firearm covered by this section a person
shall:

           (i)    Be at least:

                  (A)   Twenty-one (21) years of age if the firearm
is a handgun;

               (B) Eighteen (18) years of age if the firearm is
a shotgun or rifle.

          (ii) Not have been convicted of any felony in any
state, territory or other jurisdiction of the United States.
This paragraph shall not apply to antique firearms;

          (iii) Not currently be adjudicated to be legally
incompetent; and

           (iv)    Not have been committed to a mental institution.
