Looking for some recommendations for a new spring..currently have a systema m120s...it's pretty much done FPS has dropped to 350 I was told their springs are \"Watch your language\"..was recommended to buy mad bull and I was wondering if this is legit? If not what are some good springs.

about a year old...took it to a tech to get some work done, they did a chrono and said fps is kinda low what spring you got? I told them systema and they said it was crap..get madbull. I was wondering if this is true..if not who makes some of the better stuff out there.
I was going to let them do it at first..but it's 60 bucks just to open the gearbox so ill be doing it myself.

What was the original FPS?
Springs do set over time, and FPS tends to vary on airseal and temperature primarily. On a hot day I can get just over 400 with one of my guns, for example, whereas on a cooler day I might get about 390. Same bb weight and internal set up.

Go with the Mad Bull !!! IMHO not a better quality spring on the market for the normal Player.
SYSTEMA springs are over priced, over rated, overly taxing on the nerves, som of the biggest P-O-S, on the market.
