Technical data directly related to the manufacture or production of any defense articles described elsewhere in this category that are designated as Significant Military Equipment (SME) shall itself be designated SME.
(j) The following interpretations explain and amplify the terms used in this category and throughout this subchapter:
(1) A firearm is a weapon not over .50 caliber (12.7 mm) which is designed to expel a projectile by the action of an explosive or which may be readily converted to do so.
(2) A rifle is a shoulder firearm which can discharge a bullet through a rifled barrel 16 inches or longer.
(3) A carbine is a lightweight shoulder firearm with a barrel under 16 inches in length.
(4) A pistol is a hand-operated firearm having a chamber integral with or permanently aligned with the bore.
(5) A revolver is a hand-operated firearm with a revolving cylinder containing chambers for individual cartridges.
(6) A submachine gun, “machine pistol” or “machine gun” is a firearm originally designed to fire, or capable of being fired, fully automatically by a single pull of the trigger.
Note: This coverage by the U.S. Munitions List in paragraphs (a) through (i) of this category excludes any non-combat shotgun with a barrel length of 18 inches or longer, BB, pellet, and muzzle loading (black powder) firearms. This category does not cover riflescopes and sighting devices that are not manufactured to military specifications. It also excludes accessories and attachments (e.g., belts, slings, after market rubber grips, cleaning kits) for firearms that do not enhance the usefulness, effectiveness, or capabilities of the firearm, components and parts. The Department of Commerce regulates the export of such items. See the Export Administration Regulations (15 CFR parts 730-799). In addition, license exemptions for the items in this category are available in various parts of this subchapter (e.g., §§123.17, 123.18 and 125.4).
Category II—Guns and Armament
*(a) Guns over caliber .50 (i.e., 12.7 mm), whether towed, airborne, self-propelled, or fixed, including but not limited to, howitzers, mortars, cannons, recoilless rifles, and grenade launchers.
(b) Flame throwers specifically designed or modified for military application.
(c) Apparatus and devices for launching or delivering ordnance, other than those articles controlled in Category IV.
*(d) Kinetic energy weapon systems specifically designed or modified for destruction or rendering mission-abort of a target.
(e) Signature control materials (e.g., parasitic, structural, coatings, screening) techniques, and equipment specifically designed, developed, configured, adapted or modified to alter or reduce the signature (e.g., muzzle flash suppression, radar, infrared, visual, laser/electro-optical, acoustic) of defense articles controlled by this category.
*(f) Engines specifically designed or modified for the self-propelled guns and howitzers in paragraph (a) of this category.
(g) Tooling and equipment specifically designed or modified for the production of defense articles controlled by this category.
(h) Test and evaluation equipment and test models specifically designed or modified for the articles controlled by this category. This includes but is not limited to diagnostic instrumentation and physical test models.
(i) Autoloading systems for electronic programming of projectile function for the defense articles controlled in this Category.
(j) All other components, parts, accessories, attachments and associated equipment specifically designed or modified for the articles in paragraphs (a) through (i) of this category. This includes but is not limited to mounts and carriages for the articles controlled in this category.
(k) Technical data (as defined in §120.10 of this subchapter) and defense services (as defined in §120.9 of this subchapter) directly related to the defense articles described in paragraphs (a) through (j) of this category. Technical data directly related to the manufacture or production of any defense articles described elsewhere in this category that are designated as Significant Military Equipment (SME) shall itself be designated SME.
(l) The following interpretations explain and amplify the terms used in this category and elsewhere in this subchapter:
(1) The kinetic energy weapons systems in paragraph (d) of this category include but are not limited to:
(i) Launch systems and subsystems capable of accelerating masses larger than 0.1g to velocities in excess of 1.6km/s, in single or rapid fire modes, using methods such as: electromagnetic, electrothermal, plasma, light gas, or chemical;
(ii) Prime power generation, electric armor, energy storage, thermal management; conditioning, switching or fuel-handling equipment; and the electrical interfaces between power supply gun and other turret electric drive function;
(iii) Target acquisition, tracking fire control or damage assessment systems; and
(iv) Homing seeker, guidance or divert propulsion (lateral acceleration) systems for projectiles.
(2) The articles in this category include any end item, component, accessory, attachment part, firmware, software or system that has been designed or manufactured using technical data and defense services controlled by this category.
