What I have done was put it in my drill press and while running hold a flat file against it and file it down a bit. I used a small nail in the free end and a clamp to support that end. Poor mans lathe

You could IM tp555 here on the forum. He can make you a custom gas block that uses set screws to hole the gas tube in the block. With his you just cut off the plugged end.

Put it in the gas block. Mark for your roll pin. Drill the hole for the rollpin. Assemble. None of my tubes have a plug in them, but my guns are not what you would call normal run of the mill ARs.

are your gas blocks open on the end? the hole that the tube goes in on mine goes straight through(open on both ends)

It would be kind of hard to remove a roll pin if you only had a hole on one side.

He's talking about the gas tube hole--it goes all the way through the gas block so he needs a closed end gas tube.

No, none of them do.

To answer the original question, I don't know of any tool available to replicate the "bulge" on the end of the gas tube. I too assume the bulge is necessary to help seal the tube to the bolt key. You can get a custom sized gas tube made or simply replace your gas block with one that doesn't have a double open end gas tube hole.
