PDI VSR-10 High-Power Airsoft Spring 450-520 FPS Velocity

The PDI VSR-10 Chrome Silicon Steel Spring is engineered for airsoft enthusiasts seeking superior performance and reliability in their upgrades. Crafted from premium-grade chrome silicon steel, this high-quality spring delivers consistent power and durability while maintaining optimal efficiency during rapid firing sessions. Its variable pitch design ensures smooth operation by providing lighter compression compared to standard springs, reducing wear on your airsoft gun’s internals while enabling faster return speeds for enhanced trigger response—perfect for competitive play or demanding scenarios where precision matters most.

When paired with compatible components like PDI’s Precision Cylinder Set HD and a TM VSR original inner barrel/chamber setup, this spring has been tested to achieve impressive velocities up to 520 FPS using 0.2g BBs. However, actual results may vary depending on your specific build configuration.

Key Compatibility Details:
This spring requires careful setup to ensure seamless integration. With an outer diameter (OD) of 13mm and inner diameter (ID) of 11mm, it must be used alongside a 9mm spring guide to function properly. Additionally, its larger ID necessitates a piston with adequate clearance—PDI’s own VSR-10 pistons are specifically designed for this purpose. Before purchasing, verify that your existing parts align with these specifications to avoid compatibility issues and maximize performance gains.

Designed as an upgrade for serious users, this spring stands out from generic alternatives by combining advanced materials with tailored engineering for the VSR-10 platform. Whether you’re aiming for higher FPS or smoother mechanics, its variable pitch construction offers a balanced solution that minimizes recoil while maintaining power output over extended use. For airsoft players looking to elevate their gun’s performance without compromising longevity, this chrome silicon steel spring is an essential component when paired with compatible parts like PDI’s piston system or recommended guides.

Ensure your setup is ready for this high-performance upgrade by confirming compatibility prior to installation—your next precision-driven airsoft session starts here!
