The G36 was the German Bundeswehr's standard service rifle from 1997 onward, representing a fundamental architectural departure from the G3 — polymer construction, a rotating bolt, and a short-stroke gas piston in a clean modern package. The 18.9-inch barrel with integral carrying handle and factory optical sight made it immediately distinctive. Controversy over barrel accuracy degradation under sustained fire in hot-climate deployments accelerated its replacement by the HK433.
