Current through Register 2024 Notice Reg. No. 28, July 12, 2024
For the purposes of Penal Code section
					 29180 and Chapter
					 41, the following definitions will apply:
(a) "Barrel" means the tube, usually metal and
				  cylindrical, through which a projectile or shot charge is fired. Barrels may have a
				  rifled or smooth bore.
(b) "Barrel
				  length" means the length of the barrel measured as follows: Without consideration of
				  any extensions or protrusions rearward of the closed bolt or breech-face the
				  approved procedure for measuring barrel length is to measure from the closed bolt
				  (or breech-face) to the furthermost end of the barrel or permanently attached muzzle
				  device. Permanent methods of attachment include full-fusion gas or electric
				  steel-seam welding, high temperature (1100° F) silver soldering, or blind
				  pinning with the pin head welded over. Barrels are measured by inserting a dowel rod
				  into the barrel until the rod stops against the closed bolt or breech-face. The rod
				  is then marked at the furthermost end of the barrel or permanently attached muzzle
				  device, withdrawn from the barrel, and measured.
(c) "Bolt Action" means a firearm mechanism
				  activated by manual operation of the breechblock that resembles a common door
				  bolt.
(d) "Bore" means the interior of a
				  firearm's barrel excluding the chamber.
(e) "Break Top" means an action design wherein the
				  barrel(s) is pivoted on the frame/receiver. When the action is open, the barrel may
				  pivot up, down, or sideways for loading or unloading. When the action is closed, the
				  breech of the barrel(s) swings against the standing breech. Opening the action is
				  normally accomplished by movement of a top-, side-, or under-lever.
(f) "Caliber" means the nominal diameter of a
				  projectile of a rifled firearm or the diameter between lands in a rifled barrel. In
				  the United States, caliber is usually expressed in hundredths of an inch; in Great
				  Britain in thousandths of an inch; in Europe and elsewhere in millimeters.
(g) "CFARS" means the California Firearms
				  Application Reporting System.
(h)
				  "Conspicuously" means that all required markings shall be placed in such a manner as
				  to be wholly unobstructed from plain view.
(i) "Department" means the California Department
				  of Justice.
(j) "Firearm precursor part"
				  has the meaning set forth for that term in Penal Code section
				  16531.
(k) "Firearms Eligibility Check" means a state and
				  federal background check pursuant to Penal Code section
				  28220 that is used
				  to determine an individual's eligibility to possess, receive, own, or purchase a
				  firearm.
(l) "Frame" has the meaning set
				  forth for that term in section
				  4303, subdivision (a)(3).
(m) "FSC" means Firearm Safety Certificate as
				  defined in Penal Code section
				  16535.
(n) "Legibly marked" means using exclusively Roman
				  letters (A, a, B, b, C, c, and so forth) and numbers.
(o) "Other mark of identification" has the same
				  definition as subdivision (r).
(p)
				  "Receiver" has the meaning set forth for that term in section
				  4303, subdivision (a)(6).
(q) "Single Shot" generally means a firearm with a
				  break top or bolt action design that lacks a magazine. The shooter would manually
				  load the firearms chamber each time the weapon was fired. A variation of the single
				  shot is the single shot repeating style firearm which traditionally will have a bolt
				  action, lever action or pump action coupled with a magazine.
(r) "Unique Serial Number" means a serial number
				  issued by the Department that consists of a sequence of alphanumeric characters, is
				  easily identifiable as belonging to a privately made firearm, and is unique to each
				  firearm.
