Years ago, I bought a set of colored springs that go on top of the forearm and are screwed down with the forearm cap. Does anyone know what the colors mean. Assuming they are for light to heavy loads, but can't find what colors are for what loads. Thanks for any info.

Leon has it. The idea is use the lighter exhaust spring for heavy loads since they allow the excess gas to bleed off w/o slamming the action back. The heaviest exhaust spring keeps the gas from bleeding off in order to cycle the very light loads.
