Ultimate Mil-Spec AEG springs are manufactured out of the best steel (SiCr) available for springs. With a minimum loss in power and consistency, the Mil-Spec spring series is the ULTIMATE choice for your AEG. The Mil-Spec springs are color-coded for better identifying them when switching out the spring for different skirmishes.
The springs are designed from the start to deliver the best output while keeping its coil strength, consistency, and quality. With the closed and ground ends, the spring remains in place during use to prevent a reduction in ROF due to bending.
Available in M95, M105, M115, M125, and M135
