An air gun or airgun, is a gun that fires projectiles pneumatically with compressed air or other gases that are mechanically pressurized without involving any chemical reactions, in contrast to a firearm, which pressurizes gases chemically via oxidation of combustible propellants that generates propulsive energy by breaking molecular bonds.

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 paintball marker, also known as a paintball gun, paint gun, or simply marker, is an air gun used in the shooting sport of paintball, and the main piece of paintball equipment. Paintball markers use compressed gas, such as carbon dioxide (CO2) or compressed air (HPA), to propel dye-filled gel capsules called paintballs through the barrel and quickly strike a target. The term "marker" is derived from its original use as a tool for forestry personnel to mark trees and ranchers to mark wandering cattle.

DIANA Mayer & Grammelspacher is an air gun manufacturer founded and based in Rastatt, Germany. The company, named after Diana, the mythological goddess of the hunt, is best known for producing quality air rifles.

Field target is an outdoor airgun field shooting sport. Competitions are usually fired at self indicating steel targets placed between 9 to 50 m. There are two classes; Piston for spring-piston air guns, and PCP for pre-charged pneumatic air guns. In sanctioned competitions, the same competition rule set is used around most of the world. A small match can consist of 40 to 60 rounds, while the world championship consists of 150 rounds. It is common to use scope sights with high magnification and a short depth of field such that an adjustable parallax knob can be used to precisely determine the target distance. The target kill zones have three standardised sizes, which are 15 mm, 25 mm or 40 mm.

The Girardoni air rifle was an air gun designed by Italian inventor Bartolomeo Girardoni circa 1779. The weapon was also known as the Windbüchse. One of the rifle's more famous associations is its use on the Lewis and Clark Expedition to explore and map the western part of North America in the early 1800s.

The Kunitomo air gun was an air rifle circa 1820, by the Japanese inventor Kunitomo Ikkansai who developed various manufacturing methods for guns and also created an air gun based on the study of Western knowledge ("rangaku") acquired from the Dutch in Dejima.

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.

A potato cannon is a pipe-based cannon which uses air pressure (pneumatic), or combustion of a flammable gas, to launch projectiles at high speeds. They are built to fire chunks of potato, as a hobby, or to fire other sorts of projectiles, for practical use. Projectiles or failing guns can be dangerous and result in life-threatening injuries, including cranial fractures, enucleation, and blindness if a person is hit.

The Walther LG400 is an air rifle first introduced in 2010 as the successor to the Walther LG300. It is a PCP powered by compressed air from a removable air cylinder. It was designed as a 10 metre air rifle for indoor competition use. It has been successfully modified to 16 Joule of kinetic energy for Field Target (FT) and Hunter Field Target (HFT) outdoor use.

The Weihrauch HW 77 is an underlever-cocked, spring-piston air rifle developed and manufactured by the German sporting weapons manufacturer Weihrauch. Renowned for its accuracy, the HW 77 is widely considered the most successful underlever air rifle ever made. It is also known for its rugged construction, considerable weight and precision adjustable trigger. The gun was marketed and sold as the Beeman HW 77 in the American market.

The Weihrauch HW 45 is an air pistol manufactured by Weihrauch & Weihrauch in Germany and originally developed as a collaboration between American importer Robert Beeman and Weihrauch. It is more commonly known in North America as the Beeman P-1 after the US importers and is a large, full power air pistol with an ambidextrous grip, available in three different calibres: .177, .20 and .22. The HW 45 is suitable for informal target shooting and plinking.
