Product Information:
This is a great spring! The Guarder SP140 AEG Spring boosts your FPS by a serious amount, which is why I recommend that only those with a sniper or DMR should use this. It retains its power well and is something I'd recommend to someone looking to upgrade their FPS.

Pros:
Retains force
Super upgrade on FPS
SP 140 = M140 but for .25's

Cons:
Not really any cons, it's a simple component that does its job.

Product Information:
Bought this spring awhile back and just finally put it in my gun. There isn't much to say about it, because it is exactly what the description says it is. I installed it in my ECHO1 RedStar LMG that is nearly 2 years old. Every internal part (except for the barrel) is still bone stock. The gears, piston, cylinder, etc... EVERYTHING and it all holds up just fine with this spring! I'm getting about 450FPS with a .25gram so I am very pleased. I believe I have a very small compression issue with my cylinder since I'm pushing a higher FPS in this gun than intended so I'm pretty sure the FPS will rise a little bit after I replace that.

Pros:
Packs a punch!
Consistent FPS.

Cons:
Was longer than my stock spring, so it was just a little more difficult to get it in my gearbox.

Product Information:
I am running a A&K SPR MOD0. I was a little leary of installing this spring after reading the stories for others about stripping the piston, and burning out the motor and just basically ruining your gun, but I had to give it a shot. I am so glad that I did! I went form a 130 spring with standard setup to a whole new piston setup and air nozzle. I have not chrono it yet but I would say just by the rickashay shot that hit me, it's well above 400 with .25. Be careful, upgrade your parts it will run you around $100 for everything you need but boy howdy, it's worth it. Call them and see what you need to upgrade for your setup.

Pros:
Its a 140 spring!
Better than Systema.

Cons:
You need to upgrade your gearbox for it to work with no problems

Product Information:
Huge upgrade from stock, very stiff spring. I used this spring with a JBU m120 upgrade kit and used all the metal parts from that and element 300% torque gears and it will fire with stock battery and motor(which will be upgraded soon as my ROF took a hit). Very pleased with the power (the gun actually kicks, it's a very nice feeling and it intimidates other people)

Pros:
Well, I guess the power of it, but you kinda get to choose the different spring types.
Price was good.

Cons:
Tough to install (not compared to other upgraded springs, just compared to stock ones)
