M150 SPRING - Hard Coated - Black
After 6 months of trial and error, our product's performance has also been continuously improving. The color of our spring is not painted; it is hard-coated through a special process. Each spring is meticulously calculated using computer algorithms and rigorously tested with over 100,000 punches to ensure consistency in length and force. We want to demonstrate that our spring is not just any ordinary spring; it is a MadBull spring, known for its vibrant and distinct character.
