The two piece aluminum structure eliminates the need to tie the base piece to the powder dropper, and the assembled spring-loaded steel balls (2 of them, for smoother function) make assembly a breeze. (No more battling with trying to keep the steel ball in place which assembling the knob!)
The DAA Click-Adjustable Powder Knob V2 makes setting and adjusting your powder charge much easier and more precise. And it looks so cool too!
