德國HK G11無殼步槍，創新無彈殼設計，精密程度堪比鐘錶

G11是西德在1960年代後期開始開發，1980年代完成的無殼彈犢牛式突擊步槍項目，原意為取代HK G3成為新一代制式步槍。西德把步槍整體項目交由黑克勒-科赫負責、諾貝爾炸藥（Dynamit Nobel）負責無殼彈技術、亨索德·韋茨拉爾則負責瞄準鏡部份，三家公司組成了GSHG（Gesellschaft für Hülsenlose Gewehrsysteme）共同開發。 整個G11的開發計劃長達20年，投入經費極高，購置計劃也非同小可。正當G11完成研發之際，華沙公約組織於1990年代初解散，同時兩德實現了統一，冷戰結束。由於動用大量經費購置新槍械及新彈藥的需求突然消失，G11計劃雖然在技術上成功完成，但卻因欠缺訂單而從未大量投產。H&K也因G11的研發費用及訂單落空而陷入財政困難，1991年被英國航太的皇家軍械公司收購，但其後在2002年德國某集團向英國航太購回H&K The Heckler & Koch G11 is a non-production prototype assault rifle developed from the late 1960s–1980s by Gesellschaft für Hülsenlose Gewehrsysteme (GSHG) (German for "Association for Caseless Rifle Systems"), a conglomeration of companies headed by firearm manufacturer Heckler & Koch (mechanical engineering and weapon design), Dynamit Nobel (propellant composition and projectile design), and Hensoldt Wetzlar (target identification and optic systems). The rifle is noted for its use of caseless ammunition. It was primarily a project of West Germany, though it was of significance to the other NATO countries as well. In particular, versions of the G11 were included in the U.S. Advanced Combat Rifle program. In 1990, H&K finished the development of the G11, intended for the Bundeswehr and other NATO partners. Although the weapon was a technical success, it never entered full production due to the political changes of German reunification and lack of procurement contract.[3] Only 1000 units were ever produced, some of which made their way into the hands of the Bundeswehr. Ultimately, the German armed forces replaced the G3 with the G36
