Notes:

I found the two Phillips screws holding the butt stock to be loose. You will need a small head but long Phillips screw driver to tighten these up. I also found the motor mount hex head screws on the motor mount loose as well as the front barrel Allen head screws. When you get your BAR, spend some time tightening everything up.

Test Fire:

Stock FPS is around 285, but with the easy spring change this is not an issue. The ROF (rate of fire) was good at using an 8.4v 2000 mAh large battery.
