| Steyr Aug A2 |
| The Aug (Armee Universal Gewehr - Universal Army Rifle) was developed by Steyr-Mannlicher AG company of Austria in the 1970's and its production began in 1978. It was almost immediately adopted by the Austrian, and Australian armies as Stg.77 (Sturmgewehr 77 - Assault Rifle, model of 1977), and lately by New Zealand, Omani, Malaysian, Saudi Arabian, Irish, and other armed forces. The AUF was designed with versatility in mind: its key features include quick interchangeable barrels of different lengths (from short carbine barrel, to long and heavy Light Support Weapon/Marksman rifle barrel with bipod, ambidexterous design, (rifle may be quickly converted to be fired from the left shoulder, but this requires partial disassembly of the weapon). The AUG features an aluminum alloy receiver and polymer stock with bullpup layout and integral low-magnification 1.5X scope. The AUG features a conventional gas-operated with rotating bolt. The bolt carrier rides on two guide rods and thus is not in contact with the receiver. The left rod interoperated with the charging handle, while the right rod acts also as a gas picton. The hammer group is located in the buttstock, and made almost entirely of polymer, including the hammer itself. The hammer group is mounted in the single module, and can be replaced "at once" during field-stripping. Barrels may be removed and re-installed within seconds, even when hot, as a front grip is used as a barrel replacement handle. The Military AUG may be fired in select-fire or in full-auto modes with different trigger pulls - the short pull results in a single shot, while the long pull results in full auto fire. The safety is of cross-bolt type and is located above the triggergaurd. Some variants of the AUG may be equipped with the M203 40mm grenade launcher. Loast modification of the AUG, the AUG A2, introduced in 1997, features redesigned cocking handle and new sight rails that allows quick removal of the standard sight.
