It serves as the bolt carrier group (BCG) and partly as the receiver , and generally houses the firing pin / striker , the extractor and frequently also the barrel , and provides a mounting ...
A gun barrel is a crucial part of gun-type weapons such as small firearms, artillery pieces, and air guns. It is the straight shooting tube, usually made of rigid high-strength metal , through which a contained rapid expansion of high-pressure gas(es) is used to propel a projectile out of the front end ( muzzle ) at a high velocity.
Threaded barrels are often mounted to the receiver with a lot of torque, and will therefore generally require tools for assembly and disassembly, such as a suitable action wrench and a vise. Depending on the firearm, a recoil lug is sometimes fitted between the barrel and stock as part of the process,
Bolt: The part of a repeating, breech-loading firearm that blocks the rear opening of the barrel chamber while the propellant burns, and moves back and forward to facilitate loading/unloading of cartridges from the magazine. The extractor and firing pin are often integral parts of the bolt. Bore rope: A tool used to clean the barrel of a gun.
Sear: A sharp bar, resting in a notch (or in British: "bent") in a hammer (or in British: "tumbler"), holding the hammer back under the tension of the mainspring. When the trigger is pulled, the sear moves out of its notch, releasing the hammer and firing the gun. [1] The term "sear" is sometimes incorrectly used to describe a complete trigger ...
A break action is a type of firearm where the barrel(s) are hinged and can be "broken open" to expose the breech. Multi-barrel break action firearms are usually subdivided into over-and-under or side-by-side configurations for two barrel configurations or "combination gun" when mixed rifle and shotgun barrels are used.
At the end of the 20th century, the most widely adopted method of loading and unloading a revolver is the swing-out cylinder, invented by several people in early 1860s, not counting Daniel S. Moore's swinging barrel and cylinder assembly [12] in 1860, [13] amongst them were Charles W. Hopkins in 1862, [14] and Benjamin F. Joslyn in 1863, [15 ...
