The Specna Arms x Jvan 12:1 Gear Set is a high-quality gear set manufactured by Jvan Gear and branded under the Specna Arms name. This steel gear set, specifically designed for Ver2 and Ver3 mechanisms, is CNC machined and optimized to reduce friction and noise, which improves the efficiency and lifespan of the mechanism.
