Rheinmetall MG 3

This German-made, belt-fed machine gun works best when mounted on a tripod or vehicle, but it still looks pretty badass wielded in one hand Rambo-style. Its surprisingly short recoil is complimented by a fire rate of 1300 rounds per minute, and with an effective range of 200 to 1200 metres there's no hiding from this weapon's deadly brand of German efficiency.
