Like the title said : SHS vs Madbull springs, which one is better? M130 from both brands
Madbull = http://www.airsoftgi.com/product_info.php?products_id=2459
SHS = http://www.airsoftgi.com/product_info.php?products_id=14773
I stop trusting reviews since some get washed out from negativity.

Neither. For slightly more than the SHS and less than the madbull, you can get one of the best springs, a guarder. A guarder SP120 should be similar to an M130.

Both of my SHS spring settled 25-30fps (w/ .20g) lower than their rating, but the shot-to-shot output is very consistent.

Honestly, get a Prometheus or Guarder spring. They will hold their advertised rating longer and settle less (loose output over time) than other springs.

Also, just thought I would point this out, M ratings are in meters per second with .20g and SP ratings are in meters per second with .25g.
SP ratings are just about the same as an M rating one step higher (SP120 is very close to an M130).

Which makes prommy springs incredibly confusing.

To the Op, forget about madbull springs. They coat their springs in paint that flakes off and leaves tons of debris inside the gearbox. I've heard there're great springs, but that one fatal flaw kills the endgame.

Any site that ships to CA with guarder springs around 400-450 fps because on Evike, GI, Megastore I can't seem to find it links please. Most of the guarder springs in my range is "discontinued"

http://www.airsoftgi.com/product_info.php?products_id=1426 = Prometheus m135
Right now I'm still going with the SHS because its all I got

 

[Raven1st]

Look on Brillarmory or Clandestine Airsoft for Prommy springs, they are cheaper and they should have some of the lower powered ones.

 

[TheInfidel23]

Don't have a link, but brill armory currently has most of their Guarder springs in stock.

 

[NobleNik22]

What are the difference between SP and M is M for 0.2? or is SP for 0.25 ? So if a buy a m140 i should get a sp130?

 

[Topper]

Yes. That will be about right.
