If i strip out hex screws i take a small drill bit and drill the hole deeper. Then take the next size up hex driver and hammer it in there. Of course that method doesn't work for grub screws but you get what I'm saying.

I only strip screws on the motor grip of my m4. I have yet to mess up any others. Using quality tools, applying proper down pressure, and the angle helps out a lot btw.

Although if you're screwing into plastic...
