Spring Guide Prometheus Smoother Version 2

 With this Prometheus Smoother Version 2 spring guide you ensure that the spring of your AEG replica gets less friction inside the gearbox, increasing the performance of the replica. 

Friction is minimized thanks to the bearings located at the end of the spring guide, allowing the spring to rotate freely. This results in less wear on both the spring and the piston. In addition, the robust steel construction is provided with a special coating that reduces the degree of friction and lubricates the spring guide with every cycle.
