The VK-1 rifle is designed for exceptional reliability and performance, featuring a patented low-profile piston system that optimizes gas flow for maximum efficiency. Its advanced piston assembly incorporates a unique cup and spigot design, enhancing the gas seal and improving overall system operation.
