US parts kit regulation is distinct from that of other countries, where a firearm's pressure bearing parts such as bolts, barrels, and gas pistons are the commonly regulated components. In the United States a serialized receiver can be purchased or manufactured from a state of incompleteness to create a firearm. [ 3 ]
Front cover – The M16A1 Rifle – Operation and Preventive Maintenance by Will Eisner, issued to American soldiers in the Vietnam War. An inadequately maintained firearm will often accumulate excessive fouling and dirt within the barrel and receiver, which not only can clog up the rifling and decrease the firearm's accuracy and precision, but can also interfere with the proper operation of ...
Obturation is the necessary barrel blockage or fit in a firearm or airgun created by a deformed soft projectile. [1] A bullet or pellet made of soft material and often with a concave base will flare under the heat and pressure of firing, filling the bore and engaging the barrel's rifling.
Dry firing firearms is the practice of discharging (or simulating the discharge of) a firearm without any live ammunition, or practicing with an inert laser/infrared training platform such as an iMarksman or SIRT (Shot Indicating Resetting Trigger) training pistol, and may also include the use of a target/feedback system, such as the iDryfire or LASR software.
Wadding can be crucial to a gun's efficiency, since any gas that leaks past a projectile as it is being fired is wasted. A harder or more carefully designed item which serves this purpose is often called a sabot. Wadding for muzzleloaders is typically a small piece of cloth, or paper wrapping from the cartridge.

Belt-fed systems minimize the proportional weight of the ammunition apparatus to the entire weapon system, and allow high rates of continuous fire without needing frequent magazine changes. The capacity of belts and associated belt containers is typically a function of weight and bulk, and their size is limited by caliber and the combined ...
All smokeless powders are somewhat difficult to ignite in a gun, so that in order to prevent hang-fires every cartridge has a primer or igniter, of ordinary fine grain gunpowder, placed so as to intercept the flash from the tube; the outside of the bag containing this igniter is made of shalloon, to allow the flash to penetrate with ease. The ...
Depending on the operating mechanism, there are a number of places that limp wristing can cause a failure to cycle. Recoil operated firearms are more susceptible to failure of this type than blowback and gas-operated firearms, and lightweight polymer framed handguns are more susceptible than heavy, steel-framed or even lighter metal alloy handguns.
