Product Information:
Bought this spring for a friends gun, needing to downgrade it to 350fps to qualify for the local indoor field.

HEADS-UP!
This spring is quoted as a 330-350 fps spring(which is what 100M/S comes to. ~1 joule)
This put a brand new Echo1 m4 at 375 fps w/ .20

Pros:
Looks like a good spring
Has the non-linear windings

Cons:
Not much other than the labeling being misleading

Product Information:
I got this spring for my A&K masada which was shooting at around 370-380 fps which was a little hot for my play style. I bought this spring and now my gun shoots right around 330 fps. The spring seems very sturdy and is non-linear to make it last a very long time. Putting the weaker spring in my gun also gave it much better trigger response and a higher rate of fire. For those looking to downgrade your fps for cqb, this is the spring to get.

Pros:
Non-linear
Perfect fps for cqb (around 330)
Improved trigger response and ROF without any major, expensive upgrades to internals

Cons:
None.
 
Will this fit the echo 1 MTC 2?
The spring in the Echo 1 MTC 2 is smaller than a regular M4 spring.
