Bullet button
A pain in the crack tool that is mandatory on all AR 15 rifles sold in California that requires the magazine release button to be pushed by the tip of a bullet in order to get the magazine out. It's sole purpose is to hinder the shooter from changing magazines by the use of a standard mag release button; thus making the rifle CA legal.
So I got my new AR 15 and it sucks that i spend more time trying to take the mag out than shooting, this bullet button really sucks!
Button Bullet
When you wear an article of clothing that is way to small for you and the pressure causes a button on your clothes to come off and shoot out like a bullet
Marcus was wearing a suit jacket that was about 8 sizes too small for him and he had a button bullet almost take my head off.
