4 Element Airsoft Upgrade: M125 Grade Spring for AEG [390 - 430 FPS] *****
Nice But Could be better

"I bought this spring and have shot 15,000 Rounds with it in. The fps is 390 on the low end it said. I checked it shooting 350 with a .25 which is 1.42 Joules. 390 with a .20 bb. It didn't give me the fps I wanted but it did what it said. I wanted to be careful not to shoot hot. Now the fps listed above is on custom gun that I have pieced together. The fps was any where from 353 to 347 which is a very tight tolerance. That really has nothing to do with the spring as more of the compression. So for this spring to get the 390 min fps the gun must have great compressing. Just a heads up if your not good at compression then might want something bigger. I also was using a Reaps a+ hop up bucking so it can drop fps by a little but with a g&g green bucking it shot only about 10 fps higher. Over all its a good buy worth the money just make sure you get compression parts sealed good. only con is that you must have good compression to get the fps stated. Not so much of a con for someone that can handle the compression upgrades."

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
