Hello everyone, I have a Select Fire 10/22 80% receiver that needs finished. Specifically, I need someone in the Portland area willing to drill the barrel hole for me. This procedure requires a Vertical milling machine with a digital readout. I learned the hard way on another receiver that a drill press isn't accurate enough for this operation. I've asked a few machine shops and they both told me to go to a gunsmith. I am willing to compensate fairly.
