"Installed this into my kwa km4-RIS along with a raptor's full metal teeth piston. The gun now shoots at 470fps with .20's. Be aware that shooting anyone within 50 feet at this high of a power is extremely painful. I made my squad captain bleed pretty bad through under armor at that range. Overall though this is a spring well worth the ten dollars.

"I put this in my P90 along with a 6.03 suppressor length barrel. Shoots long and hard!

"I installed this springs on several weapons, M14, M4, G36, AK, M5, etc without problems, this spring is strong and after some use just the lost is minimal; my last two updates are in a KWA SR12 is shooting 490 fps, at rof 870 rpm, and a KWA SR10 495 fps at 875 rpm using a regular 9.6 batteries, with a lipo they are crazy hot.

Pros:
- Strong
- very sturdy material (black finish)
- minimal lost of fps after "break time"
- After 5000 rounds, still in good shape and not deformation
- Diference between shots is +/- 5 fps
Cons:
- Not at all

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.
