  • Stock springs generally tend to be low quality and wear down relatively quickly. As the coils continuously expand and contract they loose elasticity. As a result, muzzle velocity and overall performance will suffer.
  • Variable Pitch Spring
  • Mathematically Calculated Design for Best Consistency
  • The Uneven Coil Design Allows for Better Force Distribution and Improves Overall Performance
  • Made From Super High Grade Steel
  • Resists Operational Wear and Retains Elasticity
