Since most of the guns in this section will be born from an AEG... Most of the guns will have a gearbox. I'll start by saying I have always had some problems distinguishing FPS differences between springs across all of the companies.
A lot of factors can add into the FPS output of a spring such as compression, cylinder volume vs barrel length vs bore size, proper seals, piston weight and etc etc.
I found some good information here I am pulling from an archive on my home site C3. The data was originally mined from Amplified Airsoft. The list here should give you a rough estimate of what FPS a spring will give you if you are running stock internals.
Be warned of course... Running stock internals with a Guarder SP170 will strip your teeth pretty quick. But, if you've dealt with gearboxes for long enough, you should already know that =)
Again...THIS IS NOT ALL OF MY OWN DATA. I have found it to conform with most of my applications pretty closely, but either way, use it wisely. I am not responsible for your day getting ruined when you're 5 FPS over the field limit and don't have a backup!:bird:
To the best of my knowledge, I can only conclude from researching that this is advertised/marketing data provided by manufaturers.
