The Hammerhead Rifle Tool II (HHRT V II) is a handy little no-nonsense armorer’s tool that has become a welcome addition to my toolbox. I see ARs as tools for use, not for lining a safe. Although I like to build an aesthetically pleasing carbine, I am more concerned with the functionality and reliability of any carbine that I build. It’s going to get used, get dirty, and show some “character” in the long run.
