Have you tried swapping out the spring guide? I have a feeling that the outer diameter of the guide is smaller than the inner diameter of the spring allowing it too much space to bounce around and resonating in the cylinder. Take them out and see how loose it sits or if you can, measure them with a caliper. The guide should be 7mm or 9mm.
