K11 - Air burst rifle

The rifle is developed by the Agency for Defense Development and S&T Daewoo. It has been in operational use by the South Korean army for several years (2009).

The weapon consists of a semiautomatic 20mm smart grenade launcher, an underslung assault carbine firing a 5.56mm NATO round, a top-mounted computer-assisted sighting system with integrated laser rangefinder and thermal infrared night vision capabilities.

Operating in the same manner as the XM-29, the South Korean weapon has 20mm and 25mm "smart shells" that use a computer-controlled fuse. Under a self-detonation system, the 20mm round can track its target and explode several feet above it. It is also capable of puncturing concrete walls.
