"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.

"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

Evike.com Airsoft AEG Tip:
Always reset your spring by firing one shot in semi-automatic before putting it away.
M120 / 190% or stronger spring upgrade may require reinforcement of other gear box internal parts.
9.6V or Stronger battery may be required to power higher than stock springs.
