The FPS Softair ERGAL cylinder head for V2 gearbox (TC02C) is an excellent choice for airsoft enthusiasts. Made from strong ERGAL aluminum and expertly crafted using CNC machines, this cylinder head boasts a smooth surface finish thanks to the anodizing process it undergoes. It's specifically designed for airsoft guns with V2 gearboxes, such as the MC51 and G3, and incorporates two enlarged O-rings for superior sealing with all available cylinders on the market. Additionally, the built-in UREPAN bumper is highly durable and absorbs shocks from the piston head, while the yellow-colored bumper with a hardness of 60 degrees is ideal for use in DMR configurations, providing increased gearbox skeleton protection and reduced noise. This versatile cylinder head is compatible with airsoft guns from top brands like ICS, Tokyo Marui, Classic Army, and VFC.
