    Okay are you saying that you are only getting 470 fps with those parts? You don't just get a high fps by changing parts. You have to make sure you are getting perfect air seal to get high fps

    Assuming that is what he's saying, his FPS should go up because changing springs does get you higher FPS.

    Try to make sure you didnt mess up the seal while changing internal parts. You have to be careful with that. Also changing to a better spring should bump up your fps a couple of notches

    You mean change? But 470 is very high and not allowed at most fields.

    What I'm saying is that your gearbox, somewhere is leaking air. And because its leaking air, that means you don't have a perfect air seal. You should be getting a very high fps with the m150 spring but you are only reaching 470 fps. Clearly one of your parts is faulty or you do not have perfect air seal. YOU need to find where the air is leaking out from and then make it you where you get a perfect air seal.

    Ever heard of tuning? A "lego" build won't yield good performance.

    Why do you need more FPS? Unless you're using it as a sniper rifle or pretending it's a bb gun, you don't need to go over 450.

    If you're using heavier bbs, most fields chrono with .20g bbs. If you go to a chrono and shoot 510FPS with .20s, they're going to turn you away whether you use .40s or .12s.

    You don't need more FPS if you use heavier bbs. .4s will be more accurate than a .2, but they won't go as far. However, I don't think the range is effected that significantly.

    Are you using the rifle for CQB, Field or Sniping?

    At 470 FPS with a .4g in CQB (usually 20 foot minimum), the bb will most break skin.
    At 470 FPS with a .4g in Field (usually 50 feet minimum), the bb will hurt very badly, and might break the skin.
    At 470 FPS with a .4g when sniping (unsure of minimum engagement distance), the bb will work perfectly.


    Don't quote me on the above, I've only had experience with the sniping part, although I'm pretty darn sure about the rest.

    Sometimes springs are incorrectly labeled and packaged. I know people who have had this happen to them before.
