Airforce Airguns (aka. Gunpower Airguns in the United Kingdom) is an American manufacturer of pre-charged pneumatic air rifles. The company was founded in 1994 in Fort Worth, Texas. The rifles were designed to be lightweight, accurate, and inexpensive. The design also allowed easy attachment of accessories, as well be easily adjustable in power. The rifles are made largely from aluminum, but, where necessary, as in the trigger mechanism, steel is used. The barrels are manufactured by the German company . Barrels can be swapped to change either caliber or power level of the rifle.
