6,04 mm Teflon-Nickel inner barrel (509 mm, M16/AUG/SVD)
Japan's KM Head is the top among airsoft barrels. The surface of the stainless steel barrel is coated with Teflon and Nickel (TN), which ensures good slip and scratch resistance. The internal precision of 6.04 increases accuracy.
The internal barrel is a component that fundamentally affects the range and accuracy of the weapon. The smaller the inner diameter and the smoother the surface, the better the seal of the ball. At the same time, however, higher demands are placed on the use of high-quality ammunition.
