In general, identification requires a combination of all the physical characteristics of a firearm, and not just the serial number (UNODC 2015, p.82) Detailed aspects of the physical design of the rearm are also important. Other identifying features are the name of the manufacturer, branding and additional markings added during production, import or acquisition. A serial number is usually indelibly stamped on the firearm, although these are sometimes removed to hide the provenance of the firearm.

Summary of a firearm's parts and components Therefore, producing and trading of firearms parts and components shall fall under similar regulations as the firearms trading and production.īelow the description of the main firearms components is provided followed by general anatomies of firearms where these components can be identified and localized. Also, the new barrel may have a different serial number or no serial at all, this creating difficulty in the physical identification of the firearm.īy having access to various parts and components of firearms, criminals can build their own firearms by assembling the components, or they can use these components to modify or reactivate legally purchased firearms. For example, changing of a firearm barrel will make impossible the identification of a bullet fired with the same weapon since the markings of the new barrel are different from the markings of the original barrel. The barrel is linked to a receiver, which houses the operable parts of the firearm, including a magazine which holds the ammunition. The projectile or bullet (ordinary terminology) travels through the barrel by way of an explosive charge (propellant). Since replacement of these components can impact the proper identification of a firearm, their trading shall also be regulated.Ī key part of any firearm is the barrel. The key components of a firearm are those that are essential for the proper functioning and identification of a firearm. It is important to differentiate between the key components of a firearm, and the other parts and components. All firearms have a receiver, which is comprised of springs, levers and pistons. The more common parts include the barrel, magazine, hand guard, pistol grip, trigger and the trigger guard. 'All components, parts or spare parts for small arms or light weapons or ammunition necessary for its functioning or any chemical substance serving as active material used as propelling or explosive agent.' Main components of a firearmįor the practitioner, key aspects of a firearm identification include the major components, including the working mechanism both external and internal.įirearms can comprise hundreds of parts and components.
Some instruments use different terms but, basically, they refer to the same parts and components.ĮCOWAS Convention on Small Arms and Light Weapons, their Ammunition and Other Related Materials, refers to parts and components as other related materials that include: Programme of Action on small arms and its International Tracing Instrument acknowledges, which is the importance of regulating and controlling parts and components. In addition to understanding the classification of firearms, the typology and basic visual identification, your students will need to explore the nomenclature of firearms to understand the parts and how they operate.įirearms Protocol, the parts that are considered as essential to the operation of a firearm include (but are not limited to):Īny element or replacement element specifically designed for a firearm and essential to its operation, including a barrel, frame or receiver, slide or cylinder, bolt or breech block, and any device designed or adapted to diminish the sound caused by firing a firearm (…)'
