The K3 is a
light machine gun with some visual similarity to
FN Minimi and uses a standard
5.56×45mm NATO cartridge. Its greatest advantage is that it is lighter than the
M60 and can interchange cartridges with both the K1A and K2. The feed can come from either a 30-round
box magazine or a 200-round disintegrating
M27 ammunition belt. It can be used with a
bipod for the
Squad Automatic role, and fitted with a
tripod for sustained
fire support. The rear sight is adjustable for elevation and windage, and the foresight can be adjusted for elevation for zeroing. The barrel has a built-in carry handle for ease of changing the barrel. The gun is gas operated, with a rotating bolt. The weapon system was not designed for customization, due to the fact that most soldiers of the South Korean military will not see extended use of their weapons. By 2015, ROK forces were looking to obtain a new LMG, as the K3 was suffering from age and reliability issues. S&T Motiv is attempting to win the contract by modernizing the K3 with a side-folding adjustable stock, an integral
MIL-STD-1913 rail on feed cover, detachable side and underside rails, a
carbon fiber heat shield over barrel, an improved muzzle brake/flash hider, folding iron sights, and an upgraded feed system. The same improvements would also be applied to the shorter "Para" version. As of 2019, it has not been adopted for general service, but it has been suggested that special forces units could use it. == SNT Motiv K15 ==
