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 ...
A cleaning rod is a firearm maintenance tool that can be used to clean the inside (bore) of a gun's barrel, and is made in different sizes for use on different barrel lengths, calibers and gauges. It is a sturdy, long, thin, straight rod typically made of metal, rigid plastic or carbon fiber , and usually has a handle at one end for gripping ...
The exit end of a choke is smaller by some dimension than the actual bore of the barrel. This difference in diameter is the amount of constriction. For example, for a 12 gauge, the bore diameter of the barrel is nominally 18.5 mm (0.73 in), although different manufacturers do vary their as-manufactured bore from this diameter slightly.
Unprotected bore evacuators damaged by bullets have caused considerable problems in past conflicts, but up-armoring solved this problem. Bore evacuators are a common feature on most modern tanks and some self-propelled guns. The French Leclerc tank is a counterexample; it instead uses overpressure from an internal compartment to force gases ...
Gun with threaded muzzle besides a disassembled muzzle brake and thread protector. Muzzle threads is one method of fitting accessories such as flash hiders, suppressors or muzzle brakes (compensators). The applicable thread is limited to a certain degree by the bullet caliber and barrel diameter.
Muzzleloading artillery evolved across a wide range of styles, beginning with the bombard, and evolving into culverins, falconets, sakers, demi-cannon, rifled muzzle-loaders, Parrott rifles, and many other styles. Handcannons are excepted from this list because they are hand-held and typically of small caliber.
Overt combat guns, large-bore high-powered rifles, long-range handguns chambered for rifle ammunition, and action-shooting handguns designed for accurate rapid fire, all benefit from muzzle brakes. The high-powered firearms use the muzzle brake mainly for recoil reduction, which reduces the battering of the shooter by the severe recoil.
Hence the ”cleaner bullet” nickname, often misunderstood as a kind of ”cleaning bullet” added at the end of the 10 bullet package. One issue with the bullet was that a too forceful ramming may cause an expansion of the soft lead bullet inside the barrel before firing, making it very hard to remove with a worm added on the ramrod, when ...
