德国HK公司从1949年成立之初起, 就与政府采购部门开始了合作。几十年来,一直为联邦国防军生产G3突击步枪。随着G3步枪陆续退出德军现役装备,公司开始将其改成民用型运动步枪, 如0.223英寸SL6和0.308英寸SL7。HK 公司的民用枪几乎都是从军用型派生的。但是,SLB运动步枪却是例外。 Since the establishment of the German HK Company in 1949, it has begun to cooperate with the government procurement department. The G3 assault rifles have been produced for the Federal Defense Forces for decades. As the G3 rifles gradually withdraw from the German active duty equipment, the company began to change it to civilian sports rifles, such as 0.223-inch SL6 and 0.308-inch SL7. HK's civilian guns are almost always derived from the military type. However, SLB sports rifles are the exception.
