I think it has been mentioned before, but if you remove the "evil" parts, like the pistol grip for example, then you can disassemble the entire rifle for maintenance or cleaning. That includes the bullet button in the word "entire". When you go to put it back together, even in the privacy of your own home, be aware that if you install the evil parts before the bullet button is put back on, then you are building an AW, so put the bullet button back on first before you put it back together. That is how people build guns out of parts kits by the way. That is what makes it legal to do so.
