The G3/SG1 is the sniper/designated marksman variant of the HK G3 battle rifle, featuring a select-fire trigger group set to semi-automatic, a precision barrel with polygonal rifling, and a Zeiss scope. Used by Bundeswehr and numerous allied militaries, it was the German Army's primary sniper system for two decades. The G3 roller-delayed system delivers reliable function and reasonable accuracy, though it cannot match purpose-built bolt-action platforms.
