A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries.
A shotgun is a long-barreled firearm designed to shoot a straight-walled cartridge known as a shotshell, which usually discharges numerous small pellet-like spherical sub-projectiles called shot, or sometimes a single solid projectile called a 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 are also available.
In firearms terminology, an action is the functional mechanism of a breech-loading firearm that handles the ammunition cartridges, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot firearms with a closed off breech with the powder and projectile manually loaded from the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the lock.
An air gun or airgun is a gun that fires projectiles using energy from compressed air or other gases that are mechanically pressurized. This is in contrast to a firearm, which fires projectiles using energy created by burning combustible propellants, i.e. gunpowder.
Airsoft, also known as survival game in Japan where it was first popularized, is a team-based shooting game in which participants eliminate opposing players out of play by tagging them with spherical plastic projectiles shot from low-power airguns called airsoft guns.
A BB gun is a type of air gun designed to shoot metallic spherical projectiles called BBs, which are approximately the same size as BB-size lead birdshot used on shotguns. Modern BB guns usually have a smoothbore barrel with a 4.5 mm (0.177 in) caliber, and use steel balls that measure 4.3–4.4 mm (0.171–0.173 in) in diameter and 0.33–0.35 g (5.1–5.4 gr) in weight, usually zinc- or copper-plated for corrosion resistance. Some manufacturers still make the slightly larger traditional lead balls that weigh around 0.48–0.50 g (7.4–7.7 gr), which are generally intended for use in rifled barrels.
A semi-automatic firearm, also called a self-loading or autoloading firearm, 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 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, each trigger pull only discharges a single round from a semi-automatic weapon, as opposed to a fully automatic weapon, which will shoot continuously as long as the ammunition is replete and the trigger is kept depressed.
An automatic firearm is an auto-loading firearm that continuously chambers and fires rounds when the trigger mechanism is actuated. The action of an automatic firearm is capable of harvesting the excess energy released from a previous discharge to feed a new ammunition round into the chamber, and then igniting the propellant and discharging the projectile by delivering a hammer or striker impact on the primer.
Pump action or slide action is a repeating firearm action that is operated manually by moving a sliding handguard on the gun's forestock. When shooting, the sliding forend is pulled rearward to eject any expended cartridge and typically to cock the hammer/striker, and then pushed forward to load (chamber) a new cartridge into the chamber. Most pump-action firearms use an integral tubular magazine, although some do use detachable box magazines. Pump-action is typically associated with shotguns, although it has been used in rifles and other firearms as well.
A pneumatic weapon is a weapon that fires a projectile by means of air pressure, similar in principle to the operation of pneumatic tube delivery systems. The term comes from a Greek word for "wind" or "breath" (πνεῦμα).
Accurizing is the process of improving the accuracy and precision of a gun.
Airsoft guns are replica toy guns used in airsoft sports. They are a special type of low-power smoothbore air guns designed to shoot non-metallic spherical projectiles (pb) often colloquially referred to as "BBs", which are typically made of plastic or biodegradable resin materials. Airsoft gun powerplants are designed to have low muzzle energy ratings and the pellets have significantly less penetrative and stopping powers than conventional airguns, and are generally safe for competitive sporting and recreational purposes if proper protective gear is worn.
A self-loading rifle or autoloading rifle is a rifle with an action using a portion of the energy of each cartridge fired to load another cartridge. Self-loading pistols are similar, but intended to be held and fired by a single hand, while rifles are designed to be held with both hands and fired from the shoulder.
Crosman Corporation is an American designer, manufacturer and supplier of shooting sport products, with a long-standing presence in airgun design and a tradition of producing pellet and BB guns. Crosman is also a producer of many varieties of airgun and airsoft ammunition and CO2 Powerlet cartridges. In addition, Crosman sells branded, licensed products as well as a variety of airsoft guns.
Daisy Outdoor Products is an American airgun manufacturer known particularly for their lines of BB guns. It was formed in 1882 initially as the Plymouth Iron Windmill Company in Plymouth, Michigan, to manufacture steel windmills, and from 1888 started bundling BB-caliber air guns with each windmill purchase as a sales promotion. With the unrivaled popularity of their 1888-model Daisy BB Guns, the company changed the name to Daisy Manufacturing Company in 1895 and switched their business to solely producing air guns for sale. Throughout the 20th century, Daisy has been known as a company that makes and sells BB guns and pellet youth rifles. Their Red Ryder BB Gun is perhaps the best known and longest production item, which has been featured in many TV shows and movies since its introduction in the spring of 1940.
A pellet is a non-spherical projectile designed to be shot from an air gun, and an airgun that shoots such pellets is commonly known as a pellet gun. Air gun pellets differ from bullets and shot used in firearms in terms of the pressures encountered; airguns operate at pressures as low as 50 atmospheres, while firearms operate at thousands of atmospheres. Airguns generally use a slightly undersized projectile that is designed to obturate upon shooting so as to seal the bore, and engage the rifling; firearms have sufficient pressure to force a slightly oversized bullet to fit the bore in order to form a tight seal. Since pellets may be shot through a smoothbore barrel, they are often designed to be inherently stable, much like the Foster slugs used in smoothbore shotguns.
The Crosman model 1377 is a single-shot, bolt-action, pneumatic .177 caliber pellet gun, featuring a rifled steel barrel and imitation wood checkered plastic grips. The 1377 was introduced in 1977, and has been in continuous production ever since. A separately available shoulder stock converts the rather long pistol into a carbine. The 1377 is not a competition level target airgun, but its long-rifled barrel makes it fairly accurate.
The BSA Ultra is a popular, precharged pneumatic air rifle manufactured by a subsidiary of Spanish manufacturer Gamo, BSA Guns (UK) Limited and sold worldwide. Widely used for both sport and hunting it has proven itself to be both accurate and reliable. It is an unregulated, pneumatic powered air gun available in both .177 and .22 calibres and with a choice of either single shot or multi-shot. It is one of the cheapest PCP air rifles available in the market. It was designed by BSA designer John Bowkett.
The Crosman model 1322Medalist .22 Caliber Pellet Air Pistol was a single-shot, bolt-action loading, pneumatic pump-action .22-caliber air pistol, featuring a button-rifled 10.1-in. (256 mm) steel barrel and checkered plastic grips. The 1322 was introduced in 1977 by Crosman as a general-purpose air pistol for target practice and small game hunting. It was in production, in three separate manufacturing versions, until 2004, when it was discontinued from sale in the U.S.A. In 2012 the gun has been reintroduced by Crosman.
Sheridan Products Inc. was an American air gun manufacturing company. It was purchased by the Benjamin Air Rifle Company in 1977, and later purchased by Crosman in 1994.
