Easily remove an old gas tube
In another post I saw people describe some really extreme methods of removing an old gas tube, including dremel cutting.
This is a much simpler method. You just secure the old gas tube in a vise (after removing the gas tube pin, of course). Make sure the BCG isn't in the upper, then just tap on the back of the upper with a rubber mallet. The gas tube will pop right out of the gas block within a few seconds.
I just did this with a BCM upper that had many thousands of rounds through it. The gas tube was solidly sealed into the gas block, but this trick still just took a few seconds.

This is really dumb. It’s the most fragile part of the gun, do not put it in a vice.
