"I don't know how fast shooting with this spring but very sure it's a lot faster than my stock spring. Using with .4BB can go through 4~6 cardboards in 20 feet range, so be careful when you are in gameplay not to shoot the googles. It's kind of dangerous!

"I have a pdi 520 spring that is only 40 fps weaker than this one that I can pull back with just my pinky. This one I couldn't cock back more than 3 or 4 times in a row. Sadly this spring just doesn't compare to other powerful springs on the market. Not sure why it's so much harder to pull with such a slight fps boost. It was giving me more fps but not enough to justify the hard pull. Looks well made but I can't recommend it at this price.
