+1, the average effective range of a stock VSR G-spec is around 125-150 feet. Performs poorly in wind as well.
I built my super accurate laser rifle VSR-10 for about $900. But it has no external upgrades done to it.
FPS doesn't mean a whole lot when it comes to range and accuracy, it's all about compression.
For example, Amos and I have the same VSR, however he had a 6.01 650mm barrel at 470fps, and I had a 6.03 430mm barrel at 380 fps.
He had an extra 15 feet of range, and was actually slightly LESS accurate.
Optimum FPS range for .30g BB's is around 400-430fps, if your running 450-470, you need heavier BB's
