In manufacturing a barrel of small arms, broaching or button rifling method is widely applied. These methods, however, cause high production cost and technical difficulties in manufacturing in spite of their low investment cost at early stage. Thus, rotary swaging & radial forging method is studied as an alternative considering the product quality and cost effectiveness in manufacturing. In this study, barrels of small arms were manufactured by button rifling method and rotary swaging & radial forging method, and then mechanical properties of these barrels and performance of the small arm assemblies were compared and analyzed. As results, the barrel manufactured by rotary swaging & radial forging method showed higher mechanical properties including tensile strength, yield strength, and hardness compared to the barrel manufactured by button rifling method. In addition, at small arm assembly level, firing test was conducted with more than 10,000 shots, and small arm of barrel made by rotary swaging & radial forging method exhibited equivalent or higher performance in dispersion and firing rates. Therefore, it has been expected that the rotary swaging & radial forging method can be applied in barrel production.
