Armee Universal Gewehr
斯太尔AUG(德语Armee Universal Gewehr的缩写，即陆军通用步-枪)是一种导气式、弹匣供弹、射击方式可选的无托结构步-枪，是在1960年代后期开始研制的，其目的是为了替换当时奥地利军方采用的Stg.58(FN FAL)战斗步-枪。当时军方提出的要求是：精度不低于比利时的FN FAL步-枪；重量不大于美国的M16步-枪；全长不得超过现代冲锋-枪的长度；在恶劣环境中使用时，可靠性不低于苏联的AK-47和AKM突击步-枪。原打算发展步-枪、卡宾-枪和轻机-枪这3种枪型，后来又增加了冲锋-枪。http://image2.sina.com.cn/jc/pc/2003-08-04/28/3_27-28-423-646_2003080495525.jpe新武器的研制由奥地利斯太尔-丹姆勒-普赫(Steyr-Daimler-Puch)公司的子公司斯太尔-曼利彻尔有限公司(Steyr-Mannlicher GmbH, AT)负责，主设计师有三个人——霍斯特·韦斯珀(Horst Wesp，也是Glock手-枪的设计者)、卡尔·韦格纳(Karl Wagner)和卡尔·摩斯(Karl MÖser)，而奥地利军事技术办公室的沃尔特·斯托尔(Walter Stoll)上校则负责监督研制计划的进程。

只可半自动的击锤组件，由于有些执法机构不允许采用全自动武器，因此生产出这种只能单发的机构。
