"I installed this into my JG M4 with NATO tight bored AEG, and my FPS went from a wimpy 415 FPS, to an painful 506 FPS!!! If you have an AEG it needs: metal bushings, metal spring guide, reinforced piston head, torque up motor, and a 9.6v or higher battery :)

"I got this spring for my DMR build, and it does its job quite well. Im not too sure on the FPS, I still have to chrono it, but All i know is that this gun hits hard. I got Evike's Monster torque motor, with a high torque "low noise" gearset, and a 9.6 v battery. Gun sounds great. Most people say your gonna need a new full metal piston. Im using the stock one, and im doing fine for now. It will break eventually, but I would rather have the stock piston break then my new gearset, so im just keeping it in there till it has enough wear on it. Well anyway Great spring Highly recommend it for a DMR build 5/5 stars

"This is a very good spring. I got a reading of 580fps!!! before my piston teeth got stripped out. The only down side to my upgrade is i have a SR-25 V2 gearbox long type, which requires a long type piston like the one is the SR-25 and L85. The long type pistons dont come full metal teeth. So be sure to buy an full metal teeth piston with this upgrade. The Matrix full metal teeth piston is the best piston for an extreme upgrade like this

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.
