Tried search, but did not find anything on the forum. Has anyone bought and installed the new 1903A3 commercial barrel that the CMPicon is offerring? Does anyone know if the keyway slot for the front sight is cut and present? Is the barrel timed and have an index mark?. There are always pitfalls, and I would like to hear any input if you have any. The M1icon barrels I have used from them install and headspace great with no problems. Just wondering if the 03A3 barrel they offer was the same.
