I've tried Google but nothing with specific information comes up.

1. What tools (special?) are needed to properly remove and re-install the stock on an M16A2?

2. How hard is it to do?

3. What parts would I need to convert the M16A2 fixed stock to the adjustable M4 type? Would I need a special tool to attach an M4 type stock?

Thanks!
