New spring CORE variable pitch section with single and double stage.Constructed of hardened steel, has all the advantages of the springs with variable pitch (safeguarding the piston from the "first impact") but manages to keep lengths contained so you can easily get in the gearbox without having to struggle unnecessarily and with less chance of ending up...
It is finely manufactured from A class piano wire. Very durable and strong. Irregular pitch coiling for enhanced performance. Very Consistent FPS and easy to install.
