I'm in the process of buying parts for my first AR build.  I'll be using an OLL, 10rd. mag, and bullet button.  When I take it to the range, what's the proper procedure to clear the rifle between firing periods?  Usually, you have to have the bolt locked back, no round in the chamber, and the magazine removed, so the safety officer can clear it.  Since its now has a fixed magazine ala the bullet button,  is it still o.k. to remove the magazine or does this make the rifle illegal?
