Action Sport Games brings us another high quality upgrade part from their Ultimate series. These are the ASG Mil-Spec AEG Springs. These are very high quality springs designed to deliver consistent performance. These springs are made from firearm grade steel for the maximum durability and lifespan possible.
Strength - Ratings available are from M95 up to M135. Springs are color-coded for easy identification. All springs are calibrated and tested at the factory and specifications are delivered from a test gun with a 300mm precision tight bore barrel and volume matched cylinder with zero hopup engagement. Your final FPS will vary based on your parts. Professional installation is recommended.
Material - made from military grade silicon chromium (SiCr). Springs made from cheaper materials that are not treated will fatigue sooner and can possibly snap. A snapped spring can lock up your gearbox, damage other parts and cause catastrophic failure.
Progressive Coils - gives your gears a softer start which eases overall stress on mechanical and electrical components. Regular Linear spring typically do the opposite. You might not notice this but your devices efficiency will be further enhanced by using a progressive coil spring.
Closed Flat Ends - prevents alignment issues and flexing assosciated with cut springs which reduces rate-of-fire or can cause other cycling problems.
Pre-Compressed - an extra lengthy spring means less tension loss after initial install. Regular Springs can "settle" shortly after install, giving you lower fps than expected. *Warning* ASG springs are longer than competing brands and can be more difficult to install.
Black Zinc Plating - provides extra protection against corrosion.
