Taking the free floating handguard off involves some tools, and is not a "field strip" operation. You will need a vise with an appropriate receiver fixture or wood blocks, a strap wrench, and some elbow grease. Again, this isn't something that you need to do to break down and clean the rifle.
The mag base plates must be slightly pried up at the back, since there are two small indents which keep it from sliding off under normal use. Once slightly pried up, stick a pin punch in the hole at the front and slide backwards.
