Simplified diagram of a multistage coilgun with three coils, a barrel, and a ferromagnetic projectile. A coilgun is a type of mass driver consisting of one or more coils used as electromagnets in the configuration of a linear motor that accelerate a ferromagnetic or conducting projectile to high velocity.

Block diagram of inertia operation cycle, see diagram key above. As the recoil spring returns to its uncompressed state, it pushes the bolt body backward with sufficient force to cycle the action. The bolt body unlocks and retracts the bolt head, extracts and ejects the cartridge, cocks the hammer, and compresses the return spring.
Diagram of long-stroke gas operation system Long stroke gas piston, from an AK-74. With a long-stroke system, the piston is mechanically fixed to the bolt group and moves through the entire operating cycle. This system is used in weapons such as the Bren light machine gun, AK-47, Tavor, FN Minimi, FN MAG, FN FNC, and M1 Garand.
Created roughly after a year the first-known metal 3D-printed gun was produced. [24] Has the word "Reason" etched on it, along with an excerpt from the Declaration of Independence on the barrel. [25] XPR-1 [27] 2015, October Weapon: Plasma Armature Railgun: FDM David Wirth [28] First 3D printed railgun structure.
Sear shown in a revolver action. In a firearm, the sear is the part of the trigger mechanism that holds the hammer, striker, or bolt back until the correct amount of pressure has been applied to the trigger, at which point the hammer, striker, or bolt is released to discharge the weapon.
Built-up construction was the norm for guns mounted aboard 20th century dreadnoughts and contemporary railway guns, coastal artillery, and siege guns through World War II. Diagram illustrating arrangement of components of a built-up gun, in this case the British BL 6-inch Mark IV naval gun of the 1880s
A disassembled Mauser action showing a partially disassembled receiver and bolt. In firearms terminology and law, the firearm frame or receiver is the part of a firearm which integrates other components by providing housing for internal action components such as the hammer, bolt or breechblock, firing pin and extractor, and has threaded interfaces for externally attaching ("receiving ...
The A-10 engines were initially susceptible to flameout when subjected to gases generated in the firing of the gun. When the GAU-8 is being fired, the smoke from the gun can make the engines stop, and this did occur during initial flight testing. [4] Gun exhaust is essentially oxygen-free, and is capable of causing flameouts of gas turbines ...
