Systema M100

[Huge]

hi there

I want to upgrade my spring and was looking at a nice Systema M100 spring. I have a metal ICS M4 in good shape and was wondering if I would absolutely need to change other things after I put this spring? I'm also looking at a Modify S100 and a Prometheus MS100.

thanks

Systema springs break, never liked modify, but prometheus is top notch
Although you might want to look at the MS110, depending if you play indoors or out
MS100=350fps max
MS110=385fps max

Go with Prometheus. I had a Systema break inside my gun and coil itself up.. I have a thread on here somewhere showing this.

Will never buy or use another Systema spring in my guns again.

wow thanks a lot for the tips. Crazy how only a brand name makes you think its quality haha

will the fps be affected if you have a shorter barrel w/Prometheus spring? Will MS110 be good for indoor games cause I think indoor games only allows up to the maximum of 360 fps.

Use an MS100 if your going to XT, it'll put you right around 345 fps, which is fine for outdoors as well.
And it's not just the brand name, it's the experience of handling their product. I'm a CNC machinist, I know metals, and prometheus makes some of the best parts on the market.
Not to mention they have the most accurate track record for matching springs to packaging with their color coded system.
You buy any guarder spring and you have an 80% chance of it being something else lol

Our indoor at XT has a limit of 350 FPS. Some workers are assholes where they wouldn't let you play even if it goes over 350 by 5 or 10, really depends on the workers if they let you use them or not. I'd go with the m100 Prometheus spring. ICS m4 has a longer barrel, than my P90 and my p90 has tight bore and systema parts only goes 340-345. Now without the tight bore in my P90 I was only averaging 335 FPS with the m100 Prometheus spring.
