CA M24 spring comparison.

Yes, it will work.

Thanks but how would I reduce the FPS if its too high? I play in a field and 550FPS is the max.

Please put a link to the spring in question. A typical 100% spring will be far under 550 FPS usually ~300 FPS.

Man I'm sorry. I meant a 300% spring.

To reduce the power, cut one coil off at a time and use a file to sand the spot that you cut so that it's smooth. Make sure you do one coil at a time though until you get your desired FPS.

How much FPS would one cut off coil reduce? Estimate.

You sure you got an APS2 spring and not an SR2 spring? Or a different spring?

Its a CA APS 300% spring.

How is it not fitting?

The spring wont go in the piston. Its a little bigger than the stock spring.

Is it PDI in brand? That would be your problem.

No its CA APS Spring.

If I'm not mistaken, there are two types of CA Pistons and springs. I believe that the 300% spring is designed to go with their upgraded piston, which is why its not fitting.
