Excellent article - Tiger is old-school cool!

You'll notice that there's some slight differences in how each of these SMEs present the info. and their thought processes as well as actions (for example, whether they always try to work the safety as a part of their gun-handling practices).
Figure out what makes most sense to you: the methods will follow.
Oh, and through all of this, for those who have collapsible stocks on their ARs, please remember to fully collapse/"close" the stock before you mortar the gun, as a couple of the videos above warn. If you don't, you may damage the stock and/or receiver extension ("buffer tube"), which then becomes "catastrophic" in that you may well need tools to disassemble the gun and/or extra parts to replace what you broke.
Similarly, remember to always lock the charging handle against the receiver after you've manipulated it. Allowing the handle to dangle free can, in several ways, potentially cause sufficient damage to it that may again be catastrophic.
