The South Korean K11 combination 20 mm grenade launcher and 5.56 mm carbine is now entering service and is expected to be deployed in Afghanistan when South Korean troops re-enter theatre in 2011.
K11 is the first shouldered gun able to fire air-burst grenades. It is relatively compact at 86 cm long - the 20 mm barrel is 40.5 cm long and the carbine is 31 cm - and weighs 6.1 kg including its battery, but without magazines. The latter house 30 bullets and five grenades.
The grenade is available in two versions - the high explosive fragmentation K167 and target practice K168 – both weigh 100 g and are fired at a muzzle velocity of 180 m/s for an effective range of 500 m
