SP110 spring for AEG upgrade. Made in Germany for Delta Armory.

Springs are made of high quality valve wire, the same material is used e.g. for Guarder springs. Thanks to the quality material the springs achieve constant force. Maintaining the same spring force over a longer period of time tends to be a big problem with cheaper springs made in China, where the result is a consequent drop in FPS in the gun.

These springs are the ideal solution, they are not as expensive as the Guarder but at the same time have the same quality.

The springs are heat treated and have a progressive camber.
