Daewoo Precision Industries K1/K1A assault carbine is the first modern firearm developed by Agency for Defense Development (ADD) and manufactured by Daewoo Precision Industries,[2] and entered service in Republic of Korea Armed Forces in 1981.



K1 outfitted with a foregrip and scope attached via Rail Integration System.

In 1976, Republic of Korea Army Special Warfare Command (ROKASWC) requested a new weapon to replace the old M3 Grease Gun. In the following year, ADD launched a project named XB rifle, and the project aimed at the following:

  • greater firepower than SMG class
  • light weight for easy carrying
  • cost effectiveness
  • must be indigenous for improved capacity to produce military firearms independently of other nations

The prototypes were made in 1980 and entered service in 1981. However due to the design of its flash suppressor, the K1 exhibited serious problems in service with ROK armed forces, such as:

  • Excessive recoil and weak stock due to increase in firepower
  • Excessive noise and flash
  • Difficulty in aiming during night operation

These shortcomings were later fixed by the development and adoption of a new flash suppressor, which has three holes in the top right quadrant to limit muzzle flip under rapid fire and reduces flash to one-third of that of the early K1. Moreover, 3-round burst mechanism was added for improved accuracy. This new version of K1 is known as the K1A and its production began in 1982. All K1 carbines in service were subsequently modified to the K1A standard.


Although K1 uses 5.56x45mm NATO, it is classified as a submachine gun in Republic of Korea Armed Forces because K1 was intended to replace M3 Grease Gun. On the other hand, it is a shortened assault rifle or carbine due to its characteristics.


While K1 assault carbine is commonly regarded as a short version of Daewoo K2 assault rifle, it is actually different from K2 for the following reasons:


Export versions of the K1 sold in .223 Remington are known as the MAX-1 and MAX-2.[4]
