Recommended this BB
I've used the standard bullet button (BB), the Radlock, and some other no-name variation. The Assault Planet BB with the wonder wrench is by far my favorite. The wonder wrench makes it easy to install and adjust in just a few seconds. And, when permitted by law, the wonder wrench also can serve as a magazine release button that is easy to index with your finger.
