I have taken factory barrels, used a couple or 3 layers of .010 thick electric tape down the length of the barrel. I then mix up some brownells acraglas gel with some of the brown die and bed the barrel back to the stock. You will need to put a clay dam at the end of the stock to keep it from running out. Once it has cured, I pull the barrel, remove the tape and my barrel channel matches the barrel contour with a perfect free float.
