S&T Motiv Shows Off K2C1 Improved Daewoo Rifle at KDECIF 2016

    S&T Motiv, the successor to Korean defense company Daewoo Precision Industries, was showing off a new variant of their K2 rifle that equips the Republic of Korea Armed Forces, alongside the M16A1 which remains in use with second-line units. The new rifle is called the K2C1, and features a new quad accessory rail replacing the previous plastic handguard, full-length 1913 Picatinny optics rail, and AR-15-style six position collapsing butt, which also folds. The new rifle will come in two variants, short and long barreled, with 305mm (12″) and 465mm (18.3″) barrels.

    Previously, a variant of the K2 had been shown with a new rail and handguard, but the new K2C1 is distinct; gone is the integral rear sight mount, in favor of rail-mounted BUIS. The K2C1 can also mount a grenade launcher just by removing the lower handguard, unlike the K2, which required complete removal of the handguard.
