They did a great job cutting and threading a 9mm barrel for an SBR. They also installed a new FSB on a virgin barrel for me, since I needed that done I had them build the whole upper. Once again great work, I tried the upper they built and it functions great and is on target. They are fast too, both times I had my stuff back in a little over a week and that includes shipping time both ways.
