Looking to Downgrade Spring
 

Hey guys,

My gun is currently running an m120. (Just bought it) But with winter coming I need to downgrade. What's a real good quality spring that will bring me down to the indoor limit of 350ish? I've been seeing some m100 would do and all m90. If I didn't have to go to m90 I would probably just use the m100 for both indoor and out.

Thanks.

What FPS are you getting with a M120? With a M120 I've gotten anywhere between 360 and 455 fps depending on the air seal in the gun. Every 10m/s the spring is rated for will bring you up or down about 30 fps.

prometheus ms100 is max 350fps

Sorry I haven't checked in a bit. Prometheus eh. Not easy to find it seems. Any ideas where?

asia.

what brand of gun is it? do you know what motor it has? also what battery do you want to run with it?

too powerful a battery and motor with a very weak spring can cause issues.

After linking, I googled "prometheus ms100 spring" for shits, and the very first thing that came up was that link.
You sir, need to try harder. lol

Lol just get something with the name ''m100 spring/s100'' xD Might be a bit off compared to prometheus but the fps are close.

Even if your over you can just "work you spring" or take out your o-ring in your piston head if its over 350.

There are alot of springs in the market, find the m100 spring...

systema M100 is 365fps, guarder M100 could be up to 390fps (their QC is shit), and the modify M100 is around 340-350

Remember all this stuff is made in China and to no organized standard. Best read a review before buying any parts.

And "working in your spring" doesn't always work. Some springs, like prometheus, come already worked in. It's safer to assume the spring will never drop in fps. And storing the gun with the spring compressed typically doesn't reduce it's strength either.

I found this helpfull. Lots of options and ballpark FPS rates:

Just stick with a M90. With a good air seal I get 350 fps on M90s. M100 and proper air seal will put you up to 390 or more.

What the fuck
