Description

ULTIMATE – MILSPEC – M125 – Springrate 0.826N/mm
Ultimate Mil-Spec AEG springs are manufactured out of the best steel (SiCr) available for springs. With 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 skirmises. 
The springs are designed from the start to deliver the best output while keeping it’s coil strenght, consistancy and quaity. With the closed and grinded ends, the spring remainns in place during use to prevent reduction in ROF due to bending.
Available in M95, M105, M115, M125, and M135
Features: 

Military specification spring steel – SiCr – Best possible steel for springs
The calibration test has been carried out on 6.03 – 300mm barrel. Zero hopup with 0.20g BB’s.
Progressive coiling – Provides a soft start which eases stress on both mechanical and electrical parts
Closed and grinded ends – Stable straight ends minimizes side bending which reduce ROF loss
Pre-compressed – Greatly reduces power loss from initial shrinkage
Black zink plating – Only corrosion protection which does not impair spring performance
Full specification control secures exact same specification at every spring
Color coding for easy indication of individual spring grade
