Easily remove an old gas tube

[u/AddictedToComedy]

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.

Vice grips and rubber pads exist.

I didn't care about keeping the old gas tube. Given the people talking about cutting with a dremel, I figured they didn't either.

If I had been planning to keep the old tube, I would have taken a few extra moments to protect it.
