The Heckler & Koch G11 is a non-production prototype assault rifle developed from the late 1960s to the 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.
