    The short story is I upgraded a Cybergun FN Herstal SPR with Novritsch parts (because it seemed like a good idea!). Now everything works so well I need a less powerful spring in order to take it under the 320fps.
    Anyone out there have a VSR M90 spring.

    You could try just trimming your current spring. You should find that when you get it to 320 it should be more consistent, tighter grouping etc with the upgrade.

    Trimming and also heating the original spring has been tried. I still have a bit of performance to loose.
