i'm currently looking at how to make a gun LESS THAN (I know, crazy right?) 300 FPS but the only springs i see are 300-320 FPS what other parts manipulate the FPS? Thank you.

Just get 290ish M80 spring and leave it compressed overnight. Presto, less than 300 FPS!

Thanks Steevo!

I have a Guarder SP85 I purchased two years ago from ASGI and have only used it in one game.  I no longer need it and would let it go for $10 including shipping.

Maybe my seal was not tight or the chrono was off, but it only chrono'd somewhere around 250 fps the one game it was chrono'd.

Here are your options:
Stock TM spring; M80; LPEG spring; compress a low powered spring; or remove coils.
