Which end?  Do you have a way to flare the end so it can fit the gas key

Just buy a gas tube.  They are cheap!

No.  Look at both ends.  Think you can duplicate either one?  Good luck.

The gas-block end has some sort of internal piece that is swaged in the tube, so no, you can't cut it at that end.

The end at the carrier key is not flared but the area for a distance past it is reduced in diameter. Because of how it is made along with a correct tubes design and hardness, cutting and trying to duplicate the functional design is not really something I would think could be done successfully.
There was a company that made to order specialty gas tubes and lengths, but I don't remember who or know if they still offer the service.

Somewhere between carbine and mid length. I am trying to help my friend out that has a stainless barrel. I will get him to measure it tonight and see what they are.
Thanks for all the advise.

If he knows what barrel it is can it be tracked down that way?

Sounds like it may be what is called the Patrol length gas system.  Rosco uses it on some units.  You might check with them for a gas tube.

My first thought as well.

The third unique feature of the 12.5″ K9 barrel is a custom-length gas tube. Most 12.5″ barrels on the market have a carbine-length gas tube. That’s great in that it’s reliable, but as a result, it’s not the softest shooting barrel out there. Other companies have tried doing a 12.5″ barrel with a mid-length gas tube. This makes it softer shooting, but it’s perhaps not the most reliable If you are running suppressed, it can be tough to get them running correctly. We went right in the middle between carbine and mid-length, and we think it gives you the best of both worlds where it’s a very soft shooting 12.5″ barrel, while at the same time being very reliable. - Tiberious Giblin, Rosco Manufacturing
