    What are you dropping it from? You could either put it on semi and do a quick trigger pull so that the spring is left coiled, and leave it overnight or two, or you could put in a new spring.

    Second the notion. Leave the spring compressed or replace the spring with something smaller, like an m110. Or just do an intentional airleak, which I don't really advise...haha

    Install a shorter inner barrel.
    The P90 has a 247mm inner barrel. Look for something under 200mm.

    It could, but it is hit or miss. Leave it back until the game in case, or put in a new spring, or a shorter barrel. A combination in any way I'm sure would bring you down to the desired 350.

    Do you realize the purpose behind limited FPS?
    It's a safety issue.

    Circumventing the FPS limits is generally grounds for permanent ejection from most organized fields, especially CQB arenas.

    By attempting to get around these limits, you put the other players and the business at risk.

    Play with the short barrel installed or stay home.


    And no, leaving the spring compressed will not drop the FPS by 50.

    use the shorter barrel or replace the bucking with a worn out crappy leaky bucking.
