just because parts are new doesn't mean they will seal correctly.
Not all nozzles are the same length. For example a lonex nozzle vs a modify nozzle are not the same length, even if they are both for m4s.
I have also experienced a loss of 30- 40 fps with a sorbo install type 1 cylinder and shs 120 spring and 407 barrel. My next step is to possibly try a type 0 among a couple other things. I am exactly at 370fps with .2s. It's essentially the same as your setup, but the shs spring is rated on the packaging for 380-410.
I can't say enough about the lonex a1. I put one in my p90 with a 13:1 gearset and now I really want to put the same in my g36... DAT TRIGGER RESPONSE. Compression issues first however.
BB weight drastically lowers fps the higher you go in weight, but the tradeoff is consistency in accuracy. Chrono with .2s unless you know what it converts to.. the math isn't always right best to visually confirm it through the chrono.
