"Spring worked great as far as function goes. But the chrome plated coating chipped off and got all in the gear box all the way down to my motor. I had to clean out all the chrome chips out of my gear box. I sandblasted the remaining chrome off of the spring and now it is fine. If you buy this spring consider removing all the chrome before you install it. Either by sandblasting or wire wheel.

"This spring is great, but GO BY THE CHART in the description, not the title at top.
I bought this, thinking it would be b/t 390 and 420 FPS, like the title says.
I installed this spring into my G36C, along with a high torque motor, AIM TOP piston and metal cylinder head. Everything else is stock.
As soon everything was installed I chrono'd it and was shooting about 460 FPS with .20g bb's.
I went back on Evike.com, looked at the spring description and saw that the chart says 190% (M120) ~390~460 F.P.S.
Wish I saw that before I bought it. lol. That's a little too hot for a 400 FPS max field.

Pros-
Great price!!
great construction
High FPS

Cons-
Evike needs to stick to one FPS range.
GO BY THE POWER CHART in the description

"As expected. I have used 3 different types of Matrix springs so far and they have never failed me
I have used Systema and Guarder. This spring is easier to install and FPS depreciation is less.

Pro:
Easy to install (PDI length and design)
Made with sturdier material
Doesn't rust
Not overpriced like other brands

Con:
None

"This is a great spring. I bought it for my Echo-1 G36c. Be prepared though, you might want to think about getting a high torque motor. The stock motor in my G36c was not powerful enough to pull back the spring, I got off a few slow shots (it triple fed the bb's before it fired) before it broke off a metal tooth on my aluminum piston. Obviously because of this I haven't gotten the chance to chrono the new spring, but when I get a new motor and piston I'll be sure to post it. (in about 2 weeks)
