The Republic of Korea Army (RoKA) has begun fielding the domestically developed K17 5.56 mm special operations weapon, which will replace the K1A after about 45 years of service.

The K17, produced by South Korean small-arms manufacturer SNT Motiv, was unveiled in footage published by the state-owned Defense Media Agency (DMA) on its official social media channels in late August. According to DMA, an initial batch of 1,500 weapons produced in 2026 has been issued to special-mission units and is being deployed in special forces training.

DMA reported that approximately 14,000 weapons are scheduled for production in 2027 and will replace K1A weapons operated by officers, medics, and other personnel in conventional military units in a phased manner.

The K17 features a rear-mounted charging handle, a forward assist, and ambidextrous controls, including the fire selector and magazine release. In the footage, an SNT Motiv official said the design draws on experience gained from manufacturing the US-developed M16-series rifle under licence and South Korea's indigenous K-series family of small arms.

The K17 is equipped with a short-stroke gas-piston operating system and a free-floating heavy-profile forged barrel. According to the SNT Motiv official, the barrel is about 1.5 inches longer than that of the K1A, increasing the weapon's effective range to 400 m from about 300 m.

The K17 also features a five-position telescopic buttstock, a handguard equipped with Picatinny rail and M-LOK attachment interfaces, and a polymer magazine. The K17 could serve as the baseline platform for future South Korean service rifle programmes, the SNT Motiv official added.
