*AUG A1, 20 inch barrel*
The *AUG* is a bullpup assault rifle chambered in 5.56x56 mm NATO. It was adopted by the *Austrian Army* in 1978, designated as the *Sturmgewehr 77*, replacing the FN FAL.
It fires from a closed rotating bolt and uses a short-stroke gas operated action.
The AUG is *highly modular* and consists of six core interchangeable parts: the barrel, receiver, bolt carrier group, trigger group, stock, and magazine. This allows for the AUG platform to be configured as either an assault rifle, submachine gun, or light machine gun. To lower its weight, the AUG also features *aluminium and polymer* components.
Although not explicitly designed as ambidextrous, the AUG can also be configured for *use by left-handed operators* by changing the bolt to extract on the left side. The stock features ejection ports on both sides with one covered with a removable cover when in use.
The AUG does not have a fire selector and instead uses a *progressive trigger*. Pulling the trigger halfway allows for semi-automatic fire whilst pulling the trigger fully to the rear provides fully automatic fire.
The standard AUG has a scope and carrying handle integral with the receiver, which can be changed to a receiver with an integral Picatinny rail instead.
The AUG remains in use in the Austrian Army and a modified version known as the *F88 Austeyr* was adopted in 1985 to replace the L1A1 SLR and [[M16|M16A1]] in the *Australian Army*. Modified AUG A1s also remain in use in the Irish Army and New Zealand Defence Force.
