YOU ONLY LIVE ONCE...MAYBE TWICE!
this video shows how to disassemble the AR15/M16 rifle for cleaning. if anything this should show why i am so much in opposition to this being a weapon of choice for zombie disposal and why they jam so damned much when dirty. but for those who have the misfortune of owning this weapon due to high endorsment or media hype. then this should help you none the less.
