    I should have had this tool years ago. Rockey Brass was great. Super fast shipping, and great communication.

  3. Patrick

    Great tool, does exactly what I wanted it to do.

    I did a lot of research before I decided to buy this tool…. a must have if you are serious about building / maintaining the AR. It is build extremely well and couldn’t be happier. I was able to break down factory Carbine delta ring type upper which had ridiculously tight barrel nut (1/2″ breaker bar on barrel nut wrench). Love it

    Best upper receiver rod out there hands down. Shipping was fast.
