Ultimate Upgrade Spring

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 colour 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 it's coil strength, consistency and quality. With the closed and grinded ends, the spring remains in place during use to prevent reduction in ROF due to bending.

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 zinc plating - Only corrosion protection which does not impair spring performance

Full specification control secures exact same specification at every spring

Colour coding for easy indication of individual spring grade
