I was doing my finishing touches on my recently dual-modded VX-SA, when the head of one of the screws that keeps the metal plate on the bottom of the stick in place snapped off. I guess I was tightening it a bit too much. The plate is still securely in place because of the other 5 screws, but that broken off screw is going to bother me to no end until I get it replaced soon. The screw is probably around 1/8" width (just a guess). Someone recommended using easy outs, but I think that might impossible with a screw that small.
The red circle is where the broken screw is located.
