How to Remove an HK G3 Barrel

Since 1961, German company Heckler & Koch (HK) has produced this quintessential assault rifle. Many of the world's militaries have adopted the weapon as their main field rifle. It can be fired in fully automatic, single fire and, on some models, three-shot-burst mode. Mauser, CETME and HK are responsible for the rifle's design, which includes a 20-round box-magazine and a 400-yard effective range.
