Heya all,
did it ever happened to some of you, getting a spring that should give x fps and getting half of it ? or very inconsistent springs? or very consistently low? Could there ever be several really bad springs in a batch ? thanks!

I know PDI has or used to have really bad consistency between their springs.
What brand is it? |

Prometheus should be the last springs having problems.
Probably an airseal problem, an air leak somewhere. |

Is it installed in the correct direction? That can give you a lower than ideal fps but im not sure if its enough to half it...

Some can be low due to piston position. Having the piston locked back about more then half way or so, the spring will lose power if you don't shoot semi to have it returned back in place.

Sorry, not like that. I meant if you forget and leave your gun while the piston is not fully returned, you will lose power in the spring.

Also make sure the spring is installed correctly, backwards springs can cause aprox 30 fps loss (only certain ones not exact on which just yet)

airseal would be another possible problem. |

well I have 2 prometheus spring with absolutely terrible performance ( around 250 - 300 fps ) and 2 with good classic performances.
I spent months wonderwing what the fuck was wrong to figure out in the end that 2 of my springs were fucked up.They'd give terrible performance in any gun, creating jamming problems and such. All other springs I tried ( including some systema and stock ones ) gave perfectly coherent FPS with my guns. they were BNIB. Aaaargghh ! so be careful.
