smokinghole Wrote:So I have a question about the lapping tool. I'm considering an Aero Precision COP upper for the build I'm wanting to do. How would one square up the barrel mount, if out of square, with a permanent monolithic rail in the way? What would be the best way to stand off from the tool face? I imagine a drill press might be useful in this application because the chuck is skinnier than my hand held drill.

MidwayUSA sells the Wheeler version, which has a flexible shaft. I believe this would allow a drill to drive the lapping tool while offset enough to clear the upper.
