Important FPS Notice: The FPS ranges above are manufacturer/distributor estimates and should be used only as a general reference. Installing a particular spring does not guarantee a specific FPS.
Actual muzzle velocity can vary depending on barrel length and bore, cylinder volume, compression, air seal, piston assembly, hop-up configuration, gearbox setup, BB weight, and other internal components.
Always chronograph your airsoft gun after installing or changing a spring to verify that it meets your field's velocity and energy limits.
Select your desired spring strength before adding to cart.
