[Militech] Stringent Testing Paves the Way for Global Market Expansion

SNT Motiv Production Facility
Fully Automated and Running at Full Capacity

The first officially designated rifle in the possession of the South Korean military was a Japanese rifle. Following liberation, the U.S. military confiscated Type 38 and Type 99 rifles from the Japanese army. After the founding of the national armed forces in 1948, the M1 Carbine was distributed. When the Korean War ended, former President Park Chung-hee emphasized self-reliant national defense. He flew around by helicopter and designated Cheolma-myeon in Gijang-gun, Busan Metropolitan City as the location. It was a spot considered safe even in the event of North Korean artillery bombardment. In November 1973, he ordered the establishment of a munitions factory there, which later became the predecessor of SNT Motiv. Subsequently, through an agreement with Colt's Manufacturing Company in the United States, they began producing M16 rifles and gradually accumulated technical know-how. This led to the successive creation of the K-series, which became the South Korean military's main line of assault rifles.

The STSR23 7.62mm semi-automatic sniper rifle is a representative example. It was developed to strengthen infantry squad capabilities by enabling the designated marksman role. While maintaining the accuracy of the K-14 sniper rifle, the operation was changed from a bolt-action single-loading system to a gas-operated semi-automatic system, allowing for effective sniper missions. The rifle comes in two barrel lengths, 20 and 18 inches, to match different operational purposes. The STSM21 9mm submachine gun, developed for special operations, features modular barrels and stocks, making replacement easy. The use of a telescopic lightweight stock reduces the burden on soldiers. The handguard has been lightened by using rails, and it can accommodate a variety of equipment. Except for the points where the barrel is fixed, the design ensures no part of the gun touches any other component, which reduces firing impact as well.

To observe various firearm production sites, we entered the factory. There were around 200 machining tools, and the facility covered an area of approximately 6,600 square meters. A wide range of raw materials is used to produce a single rifle. The barrel, which requires high strength, is made with steel, while aluminum is used for the rifle's body to reduce weight. The method for drilling barrels from raw materials has also evolved. Whereas the focus used to be solely on boring the hole, current methods apply external pressure during drilling to enhance barrel durability and hardness.

Because of the weight of the raw materials, production workers inevitably experience physical strain. This is why SNT started introducing unmanned robots in 2018. Currently, more than 10 robots lift and transport raw materials. The rifle is composed of about 150 parts, including the barrel and bolt. Along every factory production line, machining tools for each step of the process operated non-stop.

Production team leader Jang Won said, "We can machine a 12.7mm barrel from the machining tool every 4 minutes and 30 seconds. In the days of the former munitions factory, one barrel required 50 different process steps, but now just 37 steps are needed to complete a barrel."

The finished rifles are not supplied directly to the military. They must first pass through a testing facility, where three essential evaluations are conducted: lifecycle testing, functional testing, and targeting testing. Lifecycle testing, based on the K2 rifle, requires the weapon to fire 6,000 rounds successfully. Functional testing evaluates four aspects: semi-automatic fire, automatic fire, safety, and another criterion. Targeting testing is also mandatory, requiring the rifle to achieve approximately 1.5 MOA precision, meaning all shots must hit within one inch at 100 yards.

An official from the company commented, "Personal firearms are an essential weapons system for modern urban warfare. We will continue to lead K-Defense technological advances by improving the basic shooting accuracy of our rifles."
