Firearm Modification
Firearm modification is commonly done in order to enhance various aspects of the performance of a firearm. Reasons for these modifications can range from cosmetic to functional, and can be simple operations that the owner can perform, or complex operations requiring the services of a gunsmith. Modifications performed Common modifications include: * Cosmetic and ergonomic modifications ** Replacement or alteration of grips or stocks ** Changing of sights, such as the adjustable iron sights or a telescopic sight ** Adding or removing weight to ease carrying, alter balance, or help moderate recoil ** Metal engraving or custom woodwork ** Checkering or stippling wood or metal ** Altering the metal finish, using techniques such as bluing, electroplating, or parkerizing ** Use of a shorter barrel to reduce size and weight, or a longer barrel to increase velocity * Caliber conversions ** Rechambering or rebarreling for a new caliber, such as conversions made to chamber a wildcat cartr ...

Semi-automatic Firearm
A semi-automatic firearm, also called a self-loading or autoloading firearm (fully automatic and selective fire firearms are also variations on self-loading firearms), is a repeating firearm whose action mechanism ''automatically'' loads a following round of cartridge into the chamber (self-loading) and prepares it for subsequent firing, but requires the shooter to ''manually'' actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot (in the form of recoil or high-pressure gas expanding within the bore) to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, allow it to "reset", before pulling the trigger again to fire off the next round. As a result, eac ...

Bullseye (shooting Competition)
NRA Precision Pistol, formerly known as NRA Conventional Pistol, is a national bullseye shooting discipline organized in the United States by the National Rifle Association of America. Emphasis is on accuracy and precision, and participants shoot handguns at paper targets at fixed distances and time limits. Other organizations in the United States and Canada have established rules and keep records of similar disciplines, including the Civilian Marksmanship Program (CMP) in the United States. Bullseye pistol was the inspiration for the ISSF international 25 m Standard Pistol (82 feet) event and like the ISSF pistol events, the development of skills required to shoot one-handed at and bullseye targets at , respectively, takes considerable training to achieve proficiency. Courses of fire All courses of fire are from a standing position using a one-handed grip at two different targets depending on the distance and type of match. The slow-fire targets have the 8–10 rings ...

AR-15
An AR-15-style rifle is any lightweight semi-automatic rifle based on the Colt AR-15 design. The original ArmaLite AR-15 is a scaled-down derivative of Eugene Stoner's ArmaLite AR-10 design. The then Fairchild Engine and Airplane Corporation division ArmaLite sold the patent and trademarks to Colt's Manufacturing Company in 1959. After most of Colt's patents for the Colt AR-15 expired in 1977, many firearm manufacturers began to produce copies of the Colt AR-15 under various names. While the patents are expired, Colt retained the trademark of the AR-15 and is the sole manufacturer able to label their firearms as ''AR-15''. The "AR" in Colt AR-15 stands for "ArmaLite Rifle", not " assault rifle". The Federal Assault Weapons Ban restricted the sale of the Colt AR-15 and some derivatives in the United States from 1994 to 2004, although it did not affect rifles with fewer listed features. After the term modern sporting rifles was coined in 2009 by the US National Shooting Sports F ...

M1911 Pistol
The M1911 (Colt 1911 or Colt Government) is a single-action, recoil-operated, semi-automatic pistol chambered for the .45 ACP cartridge. The pistol's formal U.S. military designation as of 1940 was ''Automatic Pistol, Caliber .45, M1911'' for the original model adopted in March 1911, and ''Automatic Pistol, Caliber .45, M1911A1'' for the improved M1911A1 model which entered service in 1926. The designation changed to ''Pistol, Caliber .45, Automatic, M1911A1'' in the Vietnam War era. Designed by John Browning, the M1911 is the best-known of his designs to use the short recoil principle in its basic design. The pistol was widely copied, and this operating system rose to become the preeminent type of the 20th century and of nearly all modern centerfire pistols. It is popular with civilian shooters in competitive events such as the International Defensive Pistol Association and International Practical Shooting Confederation. The U.S. military procured around 2.7 million M1911 and ...

Ruger 10/22
The Ruger 10/22 is a series of semi-automatic rifles produced by American firearm manufacturer Sturm, Ruger & Co., chambered for the .22 Long Rifle rimfire cartridge. It uses a patented 10-round rotary magazine, though higher capacity box magazines are also available. The standard carbine version of the Ruger 10/22 has been in production continuously since 1964,Wood, J.B., ''Firearms Assembly / Disassembly Part III: Rimfire Rifles Revised Edition'', DBI Books, 1994, p.331 making it one of the most successful rimfire rifle designs in history, with numerous third party manufacturers making parts and accessories for upgrading and customization. The 10/22's aftermarket is so prolific that a complete 10/22 can be built without using any Ruger-made components. A magnum version of the 10/22, known as the 10/22 Magnum, chambered for the .22 WMR cartridge, was made from 1998 to 2006. A .17 HMR version, the 10/17, was announced in 2004, but was only listed in the catalog for two y ...

Sporterizing
Sporterising, sporterisation or sporterization is the practice of modifying military-type firearms either to make them suitable for civilian sporting use or to make them legal under the law. Modifying for sporting use Modifying for sporting use can involve the addition of a commercial, variable power telescopic sight, the shortening of the fore-end, and (in some cases) the fitting of a new stock. Sporterised rifles may be re-finished or otherwise customized to the tastes or requirements of the individual owner- for example, shortening the barrel or rechambering the firearm in a different caliber. Integrated bayonets, if present, are removed, as are muzzle devices sometimes for legal reasons. Large numbers of military surplus rifles were sporterised in the 1950s and 1960s- especially Lee–Enfield, M1903 Springfield, and Mauser K98 rifles, which were in abundant supply after WWII, and therefore cheaper to acquire than a newly manufactured commercial hunting rifle. SMLE Mk III rif ...

Accurizing
Accurizing is the process of improving the accuracy and precision of a gun (firearm or airgun). For firearms, accuracy is the ability to hit exactly what one is aiming at, and precision is the ability to hit the same place over and over again in a repeatable fashion. Both are the goals of accurizing, which generally concentrates on four different areas: *Usability: Enhancements that give the shooter a firmer and more controlled hold on the firearm, as well as a more consistent trigger pull. Better design ergonomics is often employed, such as adjustable buttstocks and grips with more vertical angles that are natural to the human hand and wrist (e.g. pistol grip). Spirit levels are often mounted to prevent canting, which can vary the points of impact. Weapon mounts such as bipods, monopods, benchrests, shooting sticks or simply sandbags can provide a more stable and relaxed platform for the shooter, and devices such as muzzle brakes or compensators can also be used to help counte ...

Shotgun Slug
A shotgun slug is a heavy projectile made of lead, copper, or other material and fired from a shotgun. Slugs are designed for hunting large game, and other uses, particularly in areas near human population where their short range and slow speed helps increase safety margin. The first effective modern shotgun slug was introduced by Wilhelm Brenneke in 1898, and his design remains in use today. Most shotgun slugs are designed to be fired through a cylinder bore, improved cylinder choke, rifled choke tubes, or fully rifled bores. Slugs differ from round ball lead projectiles in that they are stabilized in some manner. In the early development of firearms, smooth-bored barrels were not differentiated to fire either single or multiple projectiles. Single projectiles were used for larger game and warfare, though shot could be loaded as needed for small game, birds, and activities such as trench clearing. As firearms became specialized and differentiated, shotguns were still able to f ...

Shotgun
A shotgun (also known as a scattergun, or historically as a fowling piece) is a long gun, long-barreled firearm designed to shoot a straight-walled cartridge (firearms), cartridge known as a shotshell, which usually discharges numerous small pellets (petrology), pellet-like spherical sub-projectiles called shot (pellet), shot, or sometimes a single solid projectile called a shotgun slug, slug. Shotguns are most commonly smoothbore firearms, meaning that their gun barrels have no rifling on the inner wall, but rifled barrels for shooting slugs (slug barrels) are also available. Shotguns come in a wide variety of calibers and Gauge (firearms), gauges ranging from 5.5 mm (.22 inch) to up to , though the 12-gauge (18.53 mm or 0.729 in) and 20-gauge (15.63 mm or 0.615 in) bores are by far the most common. Almost all are breechloading, and can be single-barreled, double barreled shotgun, double-barreled, or in the form of a combination gun. Like rifles, ...

Rifle
A rifle is a long-barreled firearm designed for accurate shooting, with a barrel that has a helical pattern of grooves ( rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used extensively in warfare, law enforcement, hunting, shooting sports, and crime. The term was originally ''rifled gun'', with the verb ''rifle'' referring to the early modern machining process of creating groovings with cutting tools. By the 20th century, the weapon had become so common that the modern noun ''rifle'' is now often used for any long-shaped handheld ranged weapon designed for well-aimed discharge activated by a trigger (e.g., personnel halting and stimulation response rifle, which is actually a laser dazzler). Like all typical firearms, a rifle's projectile (bullet) is propelled by the contained def ...

Carbine
A carbine ( or ) is a long gun that has a barrel shortened from its original length. Most modern carbines are rifles that are compact versions of a longer rifle or are rifles chambered for less powerful cartridges. The smaller size and lighter weight of carbines make them easier to handle. They are typically issued to high-mobility troops such as special operations soldiers and paratroopers, as well as to mounted, artillery, logistics, or other non-infantry personnel whose roles do not require full-sized rifles, although there is a growing tendency for carbines to be issued to front-line soldiers to offset the increasing weight of other issued equipment. An example of this is the U.S. Army's M4 carbine, which is standard issue. Etymology The name comes from its first users — cavalry troopers called "carabiniers", from the French ''carabine'', from Old French ''carabin'' (soldier armed with a musket), whose origin is unclear. One theory connects it to an "ancient engine of w ...
