Very IMPORTANT READ THIS!

warning:
this spring is one of the hardest springs on the market and should not be bought unless you have the following:

1.) jbu aluminum piston (full teeth) with no teeth
2.) reinforced steel teeth for jbu piston (x2)-(just incase of wearing out)
3.) systema super-torque gear set
4.) 8mm reinforced steel gearbo shell!
5.) metal spring guide with ball bearings
6.) 8mm bushings and shims
7.) area 1000 aluminum poston head or systema silent head set
8.) systema non-bore up cylinder
9.) src aluminum nozzle for your gun

Then last you should buy 2 echo 1 grease sets and use it after every 1500 rounds fired, you should use the same bb's that came with your gun, you should use a 6.02mm+ barrel no smaller or else the bb could blow-up, you should use .25g+ airsoft gi bb's (or your guns manufacturers bb;s)
or else the bb's could jam and mess up your gun. then last the reason why you need the .25g bb's or higher is because the ones below .25 grams would be easier for the wind to push out of the way...
it would be wise to never-ever use full-auto for more than 5 seconds every hour because every time you would use full-auto the gun wears out a lot faster... Try TO USE SEMI/SINGLE SHOT AS MUCH AS YOU CAN! or use full - auto like this...

3 second bursts with 2 second stopping time

if you follow these instructions your gun will last 30% longer and with the non-full auto it would last another 40% longer....
THATS 70% LONGER THAN STOCK - GUNS/UPGRADED GUNS WHEN YOU DONT USE FULL AUTO AND UPGRADE!

thanks,
lilly

Product Information:
To the writer of the first review, please do research before you ever write anything again, as what you said is completely bogus and can be qualified as total misinformation.

First off, this type of spring should only ever be used in AEG's that have been extensively upgraded to handle the massive spring tension, and also preferably to where they are semi-auto ONLY. The FPS you get from a spring like this necessitates the use of a very high torque motor as well.

Honestly this level of spring is best used in Bolt action rifles that are capable of using AEG springs because it will up the FPS of even that to over 500 fairly easily.

THE LAST THING YOU WANT TO TRY TO MAKE IS AN AEG WITH FULL AUTO CAPABILITIES SHOOTING AT 550FPS, YOU WILL HURT SOMEONE.

That being said, spring is pretty standard, does what its designed to do fairly well!

Pros:
Decent quality

Lasts a while

Will give your DMR platform a very substantial FPS increase, Just make sure to be safe with that kind of FPS

Cons:
Meant for very specific usage due to the level of velocity it gives any type of BB you will use.
 
Would this be a good spring for my Echo 1 csr?
I need a good spring for my Full Metal Echo 1 CSR to bring up the range and power. Can anyone help me??

(I have this same question)
Staff Answer:
While that spring would indeed increase your FPS, it is far too stiff for that gun. You would need to upgrade multiple parts such as: Motor, piston, bushings, and gears in order to sustain The Sp170.
